I’m using caspar “casparcg-server-v2.3.3-lts-stable”  
And I keep receiving this error (see attached)  
Everything seems to be working fine, I cant think of what could be causing this. I dont get the error with other versions of caspar, however, the other versions don’t work with HDMI output

It would be helpful if your screenshot would show the command that triggers the error.

You are getting the 400 because CCG can’t (fully) parse the command.

That screenshot doesn’t show the full commands. Post you log file.

To me it looks like you just send another empty line. Because before the error it says:

`Received message from 192.168.56.101: \r\n`.

Caspar does not understand that empty command and sends an error.
