Good afternoon, everyone!!!

I’m using CasparCG version 2.4.3 Stable LTS on Ubuntu 22.04.  
Everything was working perfectly, but suddenly I received this error in Caspar and could no longer send AMCP commands on port 5250.  
Below is the error for analysis.

Just posted an [issue](https://github.com/CasparCG/server/issues/1680) on GitHub. Let’s see what that brings.
