Please, help 😓😢😭😭😭😭 It’s not the first time i have this boring crash. The last time the only solution that i have drop is fully purge and re-install nextcloud (and with encryption module = lost all the users files). Yesterday i don’t have any [grave] problem. Today i have just lunch some `rm /media/externalStorage/*/*.part` for little cleanup my HDD. I don’t know if that play in this infernal situation, i don’t have lunch the clean command on the nextcloud data folder. Sync clients and remote storage with webdav/davfs2 has no problem for access to the nextcloud file, that concerne jut the webui. I don’t know if it’s linked, but ALL TIME when i post a file bigger than 50Mo i have “Internal Server error” and need wait the scan via cron (`sudo -u www-data php /var/www/html/owncloud/occ files:scan --all`) for the file to appear (i can see the file via the server filesystem but i think nextcloud don’t add it in the database). **Infos about server :** ubuntu-server 16.04, apache2, mariadb 10.2.x + galera3 cluster (3x Master-Master), files are hosted on one machine, redis installed but not used, encryption module enabled, nextcloud installed manually (production branch, 12.0.4). **The bug :** On some domain name (why not on all, i don’t know), after logging connexion user has a white page with following error > Internal Server Error > > The server encountered an internal error and was unable to complete your request. > Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report. > More details can be found in the server log. ![screenshot-2017_12_21-Nextcloud-BUG-webui_not_working_because_internal_server_error_after_connexion_03](https://help.nextcloud.com/uploads/default/original/2X/1/1c10048fb0ca26b2accbc7c12fddfb8046636ca6.png) Shared folder are lost/dissipear, i have recreat it. Their is NOTHING in /var/log/apache2/error.log but in /data/nextcloud.log their is some lines ``` {"reqId":"8646JWdscfcJ30qNnlui","level":3,"time":"2017-12-21T13:39:16+00:00","remoteAddr":"192.168.1.42","user":"ADMIN_USER","app":"index","method":"GET","url":"\/index.php\/apps\/files\/","message":"Exception: {\"Exception\":\"OCP\\\\Files\\\\NotPermittedException\",\"Message\":\"\",\"Code\":0,\"Trace\":\"#0 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/Files\\\/SimpleFS\\\/SimpleFile.php(104): OC\\\\Files\\\\Node\\\\File->delete()\\n#1 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/Template\\\/SCSSCacher.php(254): OC\\\\Files\\\\SimpleFS\\\\SimpleFile->delete()\\n#2 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/Template\\\/SCSSCacher.php(164): OC\\\\Template\\\\SCSSCacher->resetCache()\\n#3 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/Template\\\/SCSSCacher.php(109): OC\\\\Template\\\\SCSSCacher->variablesChanged()\\n#4 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/Template\\\/CSSResourceLocator.php(105): OC\\\\Template\\\\SCSSCacher->process('\\\/var\\\/www\\\/html\\\/s...', 'core\\\/css\\\/server...', 'core')\\n#5 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/Template\\\/CSSResourceLocator.php(57): OC\\\\Template\\\\CSSResourceLocator->cacheAndAppendScssIfExist('\\\/var\\\/www\\\/html\\\/s...', 'core\\\/css\\\/server...')\\n#6 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/Template\\\/ResourceLocator.php(76): OC\\\\Template\\\\CSSResourceLocator->doFind('css\\\/server')\\n#7 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/TemplateLayout.php(225): OC\\\\Template\\\\ResourceLocator->find(Array)\\n#8 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/TemplateLayout.php(170): OC\\\\TemplateLayout::findStylesheetFiles(Array)\\n#9 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/legacy\\\/template.php(205): OC\\\\TemplateLayout->__construct('user', 'files')\\n#10 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/public\\\/AppFramework\\\/Http\\\/TemplateResponse.php(157): OC_Template->fetchPage()\\n#11 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/AppFramework\\\/Http\\\/Dispatcher.php(113): OCP\\\\AppFramework\\\\Http\\\\TemplateResponse->render()\\n#12 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/AppFramework\\\/App.php(114): OC\\\\AppFramework\\\\Http\\\\Dispatcher->dispatch(Object(OCA\\\\Files\\\\Controller\\\\ViewController), 'index')\\n#13 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/AppFramework\\\/Routing\\\/RouteActionHandler.php(47): OC\\\\AppFramework\\\\App::main('ViewController', 'index', Object(OC\\\\AppFramework\\\\DependencyInjection\\\\DIContainer), Array)\\n#14 [internal function]: OC\\\\AppFramework\\\\Routing\\\\RouteActionHandler->__invoke(Array)\\n#15 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/Route\\\/Router.php(299): call_user_func(Object(OC\\\\AppFramework\\\\Routing\\\\RouteActionHandler), Array)\\n#16 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/base.php(1004): OC\\\\Route\\\\Router->match('\\\/apps\\\/files\\\/')\\n#17 \\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/index.php(48): OC::handleRequest()\\n#18 {main}\",\"File\":\"\\\/var\\\/www\\\/html\\\/services\\\/cloud\\\/lib\\\/private\\\/Files\\\/Node\\\/File.php\",\"Line\":122}","userAgent":"Mozilla\/5.0 (X11;

The difference I see here is, on the left side it is HTTP and the IP address you’re using and on the right side HTTPS and a domain name. Is it possible your server is not correctly configured for HTTP? ---

No i have the same problem if i tape https. I have 2 domain name for the WAN and on the first it’s working and the second it’s not working (exactly same config). Yet it’s the same configuration that worked the previous months I don’t think the problem come from the webserver (apache2 said nothing in /var/log/apache2/error.log) and last day with same config i don’t have this crash. ---

Please help it’s a nightmare 😢 i have try these solution, they not working : 1. remove all external storage 2. [clean up oc\_storages and purge oc\_filecache](https://help.nextcloud.com/t/solved-nc12-internal-server-error-after-login/13256/2) 3. [Disable theming extension and fixe the permissions on the data folder](https://github.com/nextcloud/server/issues/5129) 4. scan new files via command line the last thing i don’t have try is to restore the database from a previous backup but i has fear to destroy my cloud ☹ Edit : when i disable the extension “theming”, all domain name access are break, with the same error. Possible the problem come from the theming extension. ---

It is really strange that you don’t have any error logs after an Internal Server error. Are you sure that you are running the apache (normally “Internal Server Errors” is a heading and therefore larger)? Can you check with: `netstat -tulpen` which process binds to port 80 and 443? You just have one webserver, no reverse proxy or anything? In your place, I’d always use domain names and https-connections, even in a local network (you can set the hostname to your local ip via your dns resolver on the local network or the hosts-file of your system if it is a desktop system and always connected via local network). The database error in your logfile just says that the connection to the database server was lost. You could try to find out if the webserver run into a timeout or if the database server closed the connection. Normally, I’d expect such an error if you do a lot of file operations, it shouldn’t show up during normal usage at all. ---

In your place, I’d always use domain names and https-connections, even in a local network (you can set the hostname to your local ip via your dns resolver on the local network or the hosts-file of your system if it is a desktop system and always connected via local network). Yes i use load balancer (haproxy), internal ip is used only by windows client (where some time, for unknowed reason the hosts file don’t has effect). > [@tflidd](#): > > The database error in your logfile just says that the connection to the database server was lost. You could try to find out if the webserver run into a timeout or if the database server closed the connection. Normally, I’d expect such an error if you do a lot of file operations, it shouldn’t show up during normal usage at all. And the question is why it’s working on one hostname and has stop to work on the others if it’s a database problem (who probably affect all hostname without exception). I love nextcloud, but really it’s the second, possible the third time that crash coming on the last months. 😢 (during the last crash i have lost some old family pictures and other files ☹ ) ---

For proxy usage, you generally have set a few parameters in your config.php: > In this case, it will be difficult to run Nextcloud at the same time without proxy. The `"overwritecondaddr" => "^10\.0\.0\.1$",` could allow you to do this ([Reverse Proxy Configuration — Nextcloud 12 Server Administration Manual 12 documentation](https://docs.nextcloud.com/server/12/admin_manual/configuration_server/reverse_proxy_configuration.html?highlight=proxy)) > [@voxdemonix](#): > > possible the third time that crash coming on the last months. 😢 No idea where the crashs came from, you think they are related to this problem? Load balancers and stuff really complicate the setup, if you don’t really need them, perhaps start simple first.

Load balancers and stuff really complicate the setup, if you don’t really need them, perhaps start simple first. I don’t know any serious bugs in current versions that create data loss. I m an “old” user of nextcloud. And before it’s born i have used owncloud many month 🙂 But after has lost my machine (hardware break), i have try to re-creat a more resistant system who do not depend on a lonely machine. Their is no problem with the load balancer (i have an other webservice who actually work). And synchronisation + webdav/davfs2 work on all domain/ip internal via the load balancer or via direct connexion. The bug is in the webui. > [@tflidd](#): > > You mean you had to restore them from backup. Actually i don’t know how to restore files from Nextcloud crashing with Encryption module enabled (without encryption it’s easy, re-install nextcloud, delete the database and restore from backup). ---

> [@voxdemonix](#): > > Their is no problem with the load balancer (i have an other webservice who actually work). And synchronisation + webdav/davfs2 work on all domain/ip internal via the load balancer or via direct connexion. The bug is in the webui. It’s just an additional layer and access via the load balancer works while access through local network doesn’t. However, the internal server error is strange and you should get an error message in the logs. Did you disable logging on apache? For the error in your nextcloud log, I found a related topic on github where there were permission issues: > > > I solved the issue: > > using the command line tool to run the following command …to disable the theming app which is causing the issue: > sudo -u www-data php occ app:disable theming > > \
