Transcriber not working

Got this exception when trying to enable subtitles in call:

.env file have the following:

It seems that key problem is:

2025-01-22 07:30:57.113 INFO: [33] net.java.sip.communicator.impl.protocol.jabber.ProtocolProviderServiceJabberImpl$JabberConnectionListener.authenticated: Authenticated: false

But it unclear what is missing there. I have set:
JICOFO_AUTH_PASSWORD
JVB_AUTH_PASSWORD
JIGASI_XMPP_PASSWORD
JIGASI_TRANSCRIBER_PASSWORD
JIBRI_RECORDER_PASSWORD
JIBRI_XMPP_PASSWORD
