Asymetrical communication

[altf4arnold]

Problem :

This is my status now when sending messages and listing users :

Matrix ---------> IRC Working OK.
IRC -----------> Matrix No communication possible and no users show up in the matrix chan.

Logs :

this is the sanitised log for the bridge when I get a message from IRC to Matrix :

This is the sanitised log from the Synapse homeserver :

Related issues :

I found #581
I also found Synapse register file

What I already have done:

related to #581 , I checked the regex. It looks ok to me.

appservice-registration-irc.yaml

  aliases:
    - exclusive: true
      regex: '#irc_.*:localhost'
  users:
    - exclusive: true
      regex: '@irc_\..*:localhost'

which I think is relevant with this :

config.yaml

      matrixClients:
        # The user ID template to use when creating virtual matrix users. This
        # MUST start with an @ and have $NICK somewhere in it.
        # Optional. Default: "@$SERVER_$NICK".
        # Example: "@irc.example.com_Alice:example.com"
        userTemplate: "@irc_$NICK"
        # The display name to use for created matrix clients. This should have
        # $NICK somewhere in it if it is specified. Can also use $SERVER to
        # insert the IRC domain.
        # Optional. Default: "$NICK". Example: "Alice"
        displayName: "$NICK"
        # Number of tries a client can attempt to join a room before the request
        # is discarded. You can also use -1 to never retry or 0 to never give up.
        # Optional. Default: -1
        joinAttempts: 0

I also tried disabling the groupId as mentioned in #581 without much more result
