HTTP Post from String Table error 202

Does anyone know what error 202 is? The error lookup says unknown, and the help file doesn’t list it either.

I believe that is a response from the HTTP server. (Not PAC Control).
Looks like an ‘Accepted’ response.

Yeah, it sure looks like that, but it isn’t.

I’m working with PSG on this, but there is a knowledge base article on the issue:

The only thing is that there is no 202 response being returned to the PAC, the PAC is closing the connection prior to starting the TLS negotiation. Whatever the issue is, I need to update the firmware on this controller before further troubleshooting.
