Hello,

i am running nextcloud 28.0.1 on a self hosted proxmox LXC. I am also using a nginx reverse proxy.

Today i noticed that i have several erros in the nextcloud log

ConnectException
cURL error 35: OpenSSL SSL_connect: Connection reset by peer in connection to domain.de:443 (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://domain.de/apps/richdocumentscode/proxy.php?req=/hosting/capabilities
Failed to fetch the Collabora capabilities endpoint: cURL error 35: OpenSSL SSL_connect: Connection reset by peer in connection to domain.de:443 (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://domain.de/apps/richdocumentscode/proxy.php?req=/hosting/capabilities

I have no idear how to fix that. Can you help?

thanks for the fast answer. I am not sure how to achieve that. When i visit that URL with my browser i get this output:

{"convert-to":{"available":true,"endpoint":"/cool/convert-to"},"hasMobileSupport":true,"hasProxyPrefix":true,"hasTemplateSaveAs":false,"hasTemplateSource":true,"hasWASMSupport":false,"hasZoteroSupport":true,"productName":"Collabora Online Development Edition","productVersion":"23.05.7.2","productVersionHash":"hash","serverId":"id"}

So how can i verify that this url is available from my container? One thing i should say, the container with nextcloud is in a different network than my pc. I tried to ping the URL, but i got no response. From my pc and my container.

you’ll find useful hints in the Collabora integration guide

familiarize yourself with the technologies you use e.g. https://docs.docker.com is good starting point for Docker systems . it will help you troubleshoot and solve issues sooner than later…

you can’t ping an URL! you can ping an IP/hostname but not an URL… one can use wget/curl to access the URL from the command line but this is a different story. …and for WOPI it makes huge difference where you access the URL from.
