Unfortunately, something went wrong when jwt the token is activated

Hello
I configure jitsi meet on Ubuntu since 2016 so far no problem but, when I turned on token authentication there is a problem. you get to the room with the token generated but after 10 to 20 seconds, the communication is interrupted even when you are alone in the room. The following message appears:
Unfortunately, something went wrong

thank you in advance for your help and I remain available for further information
