GuzzleHttp Exception ConnectException: cURL error 7

Nextcloud version (eg, 20.0.5): 25.0.1
Operating system and version (eg, Ubuntu 20.04): Ubuntu 22.04
Apache or nginx version (eg, Apache 2.4.25): nginx 1.22.1
PHP version (eg, 7.4): 8.1

The issue you are facing:
Error as in the following log (GuzzleHttp\Exception\ConnectException: cURL error 7: Failed to connect to 192.168.30.232 port 443 after 0 ms: Connection refused (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://192.168.30.232/apps/richdocumentscode/proxy.php?req=/hosting/capabilities

My setup is
Internet → Reverse Proxy:443 → nextcloud 192.168.30.232:80
So all SSL termination is done on the reverse proxy and internally it is http:80 only. It seems as if collabora is trying to reach the server on :443 which is not open on the nextcloud server (collabora server installed on same ip.

So how do i tell collabora (or whatever it is, richdocuments) to use :80 and not :443?

Is this the first time you’ve seen this error? (Y/N): N

i have the same error messages with almost the same server. (Ubuntu 20.04 and Nextcloud 25.0.2)

Error Message at Nextcloud 25.0.0 - Office 7.0.0 / Built-in CODE 22.5.702 document server not loading · Issue #202 · CollaboraOnline/richdocumentscode · GitHub

P.S.: OnlyOffice works…

Hello, you can look at the error code on this site.
https://curl.se/libcurl/c/libcurl-errors.html

error 7:
CURLE_COULDNT_CONNECT (7)

Failed to connect() to host or proxy.

In my case it’s an error 6. I wonder if it’s not my DDNS which would take time to respond?
