Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can

Nextcloud version Nextcloud Hub 5 (27.0.2)
Operating system and version Linux 5.10.0-25-amd64 x86_64 on younohost

PHP

Version: 8.1.23

The issue you are facing:

Is this the first time you’ve seen this error?Y

Steps to replicate it:

Facing the problem that i cannot access Folders or files via file tab in the browser.
Files are accessible for instance in dash I can see and open a new file (note) but in File tab I cannot access the Notes folder. If I click around in Files Tab somehow i see some folders but cannot access them, sometimes I can go down one folder hierarchy but than it stops .
I am not sure if it hast to do with the upgrade to 27.0.2. or turn on the server encryption.
I upgraded first and than switched the server encryption on, but found out not until done both in browser → files that there is a problem.
so I can access files from other apps it seems just a problem within rights in File tab.

can not even access on cli nextcloud and change user

Cryx · September 4, 2023, 4:05pm

I have a similar problem. I did a fresh install for a test nextcloud, Server fresh installed with Ubuntu 22.04. First everything was like expected (It’s not my first nextcloud instance, but the first running on own hardware). But after doing the recommended server tweaks (SSL, Memcache etc…) the Cloud ended up the way that the filkes app is completly empty, just the sidebar is visible. Clikcing on recent files and then back to main view brings the folders and files up, I can open the files, but not the folders.

After two days trial an error deleted the nextcloud folder and made a new install, with checking all needed preinstall things again. Worked also well until I activeted memcache, but that ssemed to be a redis problem (couldn’t create files or folders); so I took redis out and stuck with apcu only, filkes worked then. I kept rying around, installed apps, and after some time (20 minutes or so) I was checking the main settings and got new errors (caldav, carddav). I wanted to correkt that, but the entries in htaccess were there, Nevertheless I added the entries for webfinger and nodeinfo.

Restarted the server, and the files problem was there again. I already disabled most additional apps, but without success.

So I have no idea how to solve this or if it’s a problem especially with NC 27.0.2…

Edit: I don’t use encryption, so encryption won’t be the problem to my mind…

Doprintityourself · September 6, 2023, 11:36am

Additional to the problem, not being able to access folders or files from the File Tab
Today I found out that I cannot send e-mails any more
During setup before the update I was able to send a testmail, now the send button is greyed out
even when all credentials are in !

Cryx · September 6, 2023, 2:22pm

Hm, Mail works for me.

Doprintityourself · September 6, 2023, 3:01pm

Interesting the first level is accessible I can open the pdf on the first level
but everything else in Browerser Files is locked:

Cryx · September 6, 2023, 3:14pm

Yes, my problem too. Do yoz see the files and folders when you open the files app or do you need to change the view first (like me) to see at least something? My first level folder seems to be empty, files and folders only spear if I click on recent files (what gas also no result), but clicking back on all files at least shows them then.

Doprintityourself · September 7, 2023, 8:16am

exactly the same behavior here,
If I select group folder first they show up
and afterwards then ticking on all files I get the result above not being able to go on level down.

The good question is why can I open the PDF and view so it seems the rights to view are set correct ON THE FIRST LEVEL of the Files Folder in WEBBROWSER!

If I select the notes folder RMT and select properties even that does not give any information the property window that appears on the right side is completely empty
So this means everything in the filesystem and even in the encryption on server side that is enabled , there is no problem otherwise the file wouldn’t be in the client decrypted and editable.

Just created a note and I can edit and write and it is saved.
If I go to my windows client directory I find in the notes directory the new sub category I created as a sub folder and can see edit and view the note!!

So to narrow down I don’t believe any more that this is a problem with the server encryption.

Something has been messed up the the file rights in the www-data folder !!!

And es I already said send and receive used to work and has stopped as well.

So what is wrong with the update!

Please help somebody My family cannot access files any more!!

Cryx · September 7, 2023, 9:53am

I found the solution, at least for me. Do you have the eBooks app installed? Disabeling that solved the problem. Maybe there ate other apps too, I’m not right through testing all Apps I want. But as I have these problems on a freshly installed server with a freshly installed Nextcloud and ran into the same problem ever and ever again I did another try and installed NC without Apps in setup process. I then installed only Apps from the recommend tab, and the problem was there again. So I disabled all apps and started a step by step process - enabling an app and look if files work, if yes enable the next one.

So as disabling apps doesn’t affect stored data simply deactivate/disable all apps and turn them active again with checking the behaviour of the files app after ever activation.

But as said above, if you have the eBook app active start with disabling these.

Doprintityourself · September 7, 2023, 10:28am

WTF!!
Cryx you are genius!
Thank you so much you saved my day!!!

Yes I could remember that I some-when clicked and installed it

So for every other user whom this screws up his nerves:
I disabled the frickin ebook app

and voila
I can access my files in nextcloud Webbrowser Files again

Thanks so much
Is there a process to log this as a bug, I am not familiar with!?
And I will change the topic line to this!

Doprintityourself · September 7, 2023, 10:43am

but ,
still I cannot send any e-mails any more

Send button stays always grey
even after disabling epub viewer

Cryx · September 19, 2023, 4:06pm

The epub viewer app got an update today. Our prevoius problem seems to be solved with that version, I can access all my files. But I also updated Nextcloud itself to 27.1 in the meantime.

Doprintityourself · September 20, 2023, 8:51am

Thanks I will test it as soon as possible,

Sorry to ask, but do you ever have experienced that first created user can send in the mail system of Nextcloud but later created ones (after an update!?) cannot!
Any idea?

Appreciate your knowledge

Cryx · September 20, 2023, 9:47am

Mail app or from Admin settings?

Doprintityourself · September 20, 2023, 12:23pm

Inside nextcloud:
From mail app of each user
older user can send and receive mails, (created in yunohost admin console) , activated and used inside NC some time ago,

newly created (or jjust activated inside NC ) don’t

new user created in yunohost and activated in NC (so credentials inside auto creation process for mail run through and accepted everything fine) but,
cannot send or receive mails
The last test was to activate the first user (admin) in NC Mail, because never used and
“he also cannot send and receive mails.”
Conclusion somewhere in between and update may be has gone something wrong within Nextcloud and the mail accounts now created or activated are not able to send or receive mails.

the other option do you mean this:

never touched it, but as you say now gonna try…

Cryx · September 20, 2023, 1:08pm

In the picture are the main settings for your instance to send mails for password resets, email 2FA, Email notifications. These can be done here or direct in config.php.

I never really used the mail client or setting up auot-mail-accounts, so I can’t help with that right now, sorry.

Doprintityourself · September 20, 2023, 1:24pm

no problem, thank you for your time to answer
