Matrix.org Rooms from my Server?

[toto.s]

@girish I see the same problem here!
I use the server, Riot for Linux Desktop and RiotX on my Galaxy S20.
The server has 4096 MB Ram available

Hey @girish - yeah, it's matrix+synapse ... trying to search rooms on matrix.org. My local rooms seem okay.

[girish]

@doodlemania2 @toto-s Trying to reproduce it locally

[girish]

On my install, I got a different error:

I cleared the browser cache and the listing started working.

But joining a room fails:

[girish]

As @msbt said, joining smaller rooms (~1k participants) works. If I join larger rooms, the server runs out of memory and I get the CORS error in the UI.

17:05:07 - 2020-06-03 00:05:07,447 - synapse.http.matrixfederationclient - 165 - INFO - POST-109 - {PUT-O-160} [matrix.org] Completed: 200 OK
17:05:13 - /app/pkg/start.sh: line 80:    95 Killed                  

I bumped up the app's RAM to 2GB and I can connect to all rooms.

@doodlemania2 @toto-s Did you change the location/domain of your matrix install by any chance? If so, I think I have a guess as to what is causing the problem. Do you have a file named /app/data/configs/signing.key ?

[toto.s]

Yes, the signing.key file exists!

[girish]

Mmm, I am out of ideas here. Out of curiosity, have you guys already tried re-installing? I can't find any related issue on matrix issue tracker either.

Can you try re-installing and try to reproduce this? If it's reproducible, can you give me access (support -> enable remote support) and send us a mail at support@cloudron with the domain name. Thanks!

[doodlemania2]

Will do so today to see if I can make it go!

[doodlemania2]

Yeah, reinstallation gave the same error Riot failed to get the public room list. No key for thedoodleproject.net with ids in ['ed25519:a_HtQW'] (min_validity 1591297300437)...sadness. Will email ya.

got the same error when I try to search in Matrix

also if I try to join public group such as: #techlore:matrix.org
https://riot.im/app/#/room/#techlore:matrix.org

the result is:

[girish]

@JOduMonT The M_UNKNOWN issue is related to memory limit. When you join large matrix groups like techlore, you have to bump the memory limit to atleast 2-3GB. Can you try joining a smaller group as well?

[girish]

@doodlemania2 I replied to you from support couple of days ago, I need access to your server to debug further

[girish]

@doodlemania2 Thanks for giving access to your server. The issue was that federation setup was incorrect:

• @doodlemania2 had setup the well-known correctly
• But there was no app installed on domain.com. Without this, Cloudron will not respond to domain.com and thus the well-known setup won't work.
• To fix: I installed a dummy app on domain.com. I then checked in https://federationtester.matrix.org/ that the setup was correct.
• I waited for couple of hours since matrix.org seems to cache the DNS a bit and it had cached the previous NXDOMAIN. After that it works.

@toto-s Can you check with federation tester?

It's working now:

[doodlemania2]

Well that's outstanding! I guess suggest would be to add that requirement to the instructions for Matrix app?

[girish]

Yeah, I think this can be avoided by having some .well-known UI in cloudron. Currently, it seems a bit complicated to explain (this is actually in our docs, but I guess it's not easy to follow)

[toto.s]

@girish I sent you an email with my domain!

@girish said in Matrix.org Rooms from my Server?:

@JOduMonT The M_UNKNOWN issue is related to memory limit. When you join large matrix groups like techlore, you have to bump the memory limit to atleast 2-3GB. Can you try joining a smaller group as well?

I gave 3GB to Riot and 3GB to Matrix and logout and login but I still have this error.

[girish]

@JOduMonT Are you able to join other groups?
