Jigasi Transcription - Cannot connect to XMPP

We’ve got a multi-bridge setup running on a secure domain and are now trying to add transcription / closed captions.

In the Prosody log we can see that the jigasi user has authenticated but get the following error in the Jigasi log

We have purged/reinstalled several times but end up in the same place.
Any suggestions?

Check the password you have here; it should be the base64 conversion of your registered jigasi password:

net.java.sip.communicator.impl.protocol.jabber.acc-xmpp-1.PASSWORD=

Thanks for the suggestion.
I still get the same errors after a reboot.

Check the first point…
