@msbt I can test if there is a need for that.

[murgero]

@msbt I noticed this app does not actually have Riot front end? Also is the identity server implemented?

Edit: for the federation errors, here is my relevant log line(s):

[msbt]

@murgero yes, the riot frontend is here: https://git.cloudron.io/msbt/riot-app - the devs suggested not to run both on the same machine, splitting the apps was the way to go. The identity server is also not implemented (yet), so the registration uses vector.im at the moment.

Thanks for your input, I'll review the changes and try to figure out the point where the federation stopped working.

[yusf]

Also check my log records in https://forum.cloudron.io/post/3817

[murgero]

Any news on federation?

Edit: I know the devs for Cloudron recommended that these apps be separated, however I believe they would be better together (maybe a 3rd app that includes both?) because:

• Users can get confused on the domains (logging into riot.example.com, but user is matrix.example.com)
• Having them in the same place can allow for better troubleshooting, and in some cases, is just more convenient.
• Easier to update both at the same time, then to have to rebuild the app twice.

[msbt]

This is no recommendation from cloudron, but from the riot-devs themselves: https://github.com/vector-im/riot-web#important-security-note

I didn't have time to look further into the federation issue, maybe I'll find some time this weekend, sorry for the delay.

[murgero]

@msbt Ah my bad on misinterpreting that. and No worries. This is awesome work and worth the wait!

[yusf]

Recently learned that federation is needed for integrations to work so it's important for any integrations as well.

[msbt]

Weirdly enough, integrations are working, but federation is not... Is it possible, that the requests are being denied by cloudron and not the app @nebulon @girish? I remember we had the embedding feature which got removed and will eventually be replaced with CSP. I've tried several things, but I don't really know how to fix it... I'll jump on the matrix network and ask there if they have a clue.

[girish]

@msbt Is there anything in the browser console? CSP/X-Frame related issue will be printed in browser console.

[msbt]

federation is working, thanks to the help of the synapse admins and community! Please grab the latest version from here and let me know if it also works for you. You might need to adjust the homeserver.yaml again, probably best if you install a fresh one and compare the config. There might be some finetuning required for preview and such, but since I'm on vacation, that's a topic for another day

[murgero]

@msbt That's weird, I installed a fresh Matrix server, still getting error 500 XHR requests when trying to federate to another room off-server. (though I can list rooms now???)

[murgero]

Alright so federation is working but some rooms don't (maybe they time out because a bridge is down??)

[yusf]

@msbt Many thanks! Can’t wait to try it.

[technotame]

I have the same issue as @murgero, I can now see federated rooms, but I get an error when trying to join them.

[murgero]

@technotame what's weirder for me is that a few rooms work.

[msbt]

I've tried several channels in both directions and it was looking good. Make sure to clear your caches and maybe give the servers more ressources regarding ram, bigger channels are very hungry.

[murgero]

@msbt yea, my container has 4GB ram. Cache was cleared and new app installed (to avoid configuration issues)

[msbt]

@murgero what's the errormessage in that case? For me it said that it can't preview the room, but joining is no problem afterwards.

[murgero]

@msbt some are "This room cannot be previewed, you must join to continue" where others are "This room is unavailable at this time"blah blah with similar output in the error logs as I mentioned above.
