Collabora Online stops working after restart (502 Bad Gateway)

[nebulon]

very strange that I cannot reproduce this anywhere. Can't see why it would try to load some private key in the first place. Did you tweak any of the configs?

[archos]

@nebulon No, I haven’t manually modified any configuration files. Everything was set up through the Cloudron interface.

I have tried reinstalling Collabora multiple times, even on a different domain, but the issue persists. After installation, it works fine, but after a restart, it stops responding.

The only changes I made were increasing the memory allocation and connecting multiple Nextcloud instances.

I have tried to reproduce this with two nextcloud instances having office documents open and restarting collabora various times. Unfortunately I cannot reproduce any of those bits. Are you able to reproduce this on the demo cloudron?

@nebulon Hi,
I tried the demo instance of Collabora, but after a restart, I get the same error. I must be doing something wrong, but I really don't know what.

I logged into Collabora and added my two Nextcloud domains: app1.demo.cloudron.io|app2.demo.cloudron.io. After a restart, I can no longer connect.

At least now we know that the issue is somewhere on my side.

I also tried a fresh Nextcloud installation. My first Nextcloud instance is on the main domain, so I thought that might be the issue, but even with the new instance I have the same problem.

After restarting the Collabora app, the same error appears again.

It seems like someone had a similar issue here

[nebulon]

Aha, so possibly then changing the domain from default could be causing the issue. I didn't attempt that, since the test nextcloud instances are on the same main domain. Lets see if I can then reproduce it...

[nebulon]

I can now reproduce this by setting explicit domains. We have to debug and hopefully fix the package then. For the time being whildcard subdomains curiously seem to work fine as a workaround.

[msbt]

@nebulon can you also test it it multiple domains? I remember having issues with that a while back

[nebulon]

We've pushed a new app package. If collabora is broken in your case, just delete the file coolwsd.xml via the cloudron filemanager and restart the app. Then reconfigure if needed via its configure form.

@nebulon Wow, everything is working now! Thank you so much for your time and for fixing the app.

Just a quick question – for connecting a Nextcloud instance running on a different server, is it enough to just add the IP address of the server where Collabora is running to the WOPI allow list?

[nebulon]

As far as I understand the domain will be verified with WOPI so probably add that, but then again I guess just give it a try.
