XMPP Client not connecting with ejabberd 18.12.1-2

Add-ons Bindings

Hi everyone,

I got ejabberd 18.12.1-2 on a debian system running quite well for about 2 years.
Just now I tried to setup the xmppclient addon for openhab2 with limited success.

The xmppclient fails to authenticate with the following error:

2019-12-21 19:40:36.981 [WARN ] [oftware.smack.AbstractXMPPConnection] - Connection XMPPTCPConnection[not-authenticated] (0) closed with error

The log on ejabbered refers to an invalid token:

2019-12-21 21:19:20.128 [info] <0.370.0>@ejabberd_listener:accept:238 (<0.671.0>) Accepted connection 192.168.0.100:2565 → 192.168.0.231:5222

Since I did not use x-auth2 before I followed the instructions here for the setup: https://docs.ejabberd.im/developer/ejabberd-api/oauth/

Any ideas where to look into next ?

Cheers,
Ludwig

I’m having a similar issue connecting to the google xmpp backend. Did you ever resolve the OAUTH error?

No unfortunately I did not find any solution to that.
I even opened a thread in a more fitting environment without any result:
