I have NextCloud and Collabora spun up. Hostnames and Let’s Encrypt certs are configured via HA Proxy on pfSense. However, I’m having trouble connecting Collabora to NextCloud.
I can get an “OK” message when I visit the Collabora URL.
Within the NextCloud settings, I chose the “User Your Own Server” settings and enter “https://collabora.mydomain.com”. I get the green checkbox confirming it’s all valid.
However, when I actually attempt to edit a document, I get a browser pop-up with a connection warning which leads to a blank white screen. I’m guessing this is probably an issue with HAProxy.
I’ve never used HAProxy with Nextcloud/Collabora although I have used nginx and traefick as reverse proxies. Are you using Collabora docker or something else? Collabora is extremely tempermental and I hate when it comes time to upgrade either Nextcloud or Collabora. I had Collabora running within a VM however just later converted my setup to the VM running docker and then Collabora docker. Can you reach the collabora statistics page?
In Safari, it’s a browser pop up that says “this is a non-secure form”, but I can click through it and just get to a blank page. In Firefox, I don’t get the error message, I’m just re-directed to a black (white) page and can’t edit the document.
