Messages from Matrix missing in Gitter room - Messages federating too slow to be accepted
As reported by Oliver, https://gitter.zendesk.com/agent/tickets/18474,
Some messages from Matrix in !byOPbhowQZMlsdsksE:chat.odin.cse.buffalo.edu
(Vizier) are missing in the Gitter room, https://gitter.im/VizierDB/community.
Update: Appears to be a "Messages too old" problem where messages from chat.odin.cse.buffalo.edu
take 30+ minutes to federate with the gitter.im
homeserver, see section at the bottom of the issue description.
Federation problems
Part of the problem appears to be federation issues between gitter.im
and chat.odin.cse.buffalo.edu
. If I look at the gitter.im
homeserver, some of the messages that are missing on Gitter, never reached the gitter.im
homeserver.
It would be good to check whether the events arrived but are soft-failed for some reason on the gitter.im
server.
Messages too old
I'm not sure if this is happening but my hunch is another problem is if we're seeing federation problems, we are probably also be seeing messages come in extremely late to our gitter.im
homeserver. In the Gitter bridge, we ignore any events older than 30 minutes.
For example, notice the latest 2 messages which are not on Gitter or the gitter.im
homeserver.
