No connection after Libertime update. libretime can't reach icecast and writes that the problem is in Liquidsoap

No connection after Libertime update. libretime can’t reach icecast and writes that the problem is in Liquidsoap. (Unable to connect to the streaming server Problem with Liquidsoap) At the same time, the system status is all green, everything is installed and working correctly. The settings site is on a new server without a domain name. Only on the IP address.

Please help us in solving this problem - this is the second attempt to update the system in two years. Two years ago, the update failed. I had to go back to Ubuntu 16 and LibreTime 3.0.0 alpha 8
