tsp Generic module doesn't get connection

[wolferl62]

I have a problem with the connection between the tcp/udp Generic and the tsp Generic module in general and with a Raspberry PI in detail.
I have a device which I can only control with companion/streamdeck via RS485/232.
I installed tcp/udp and tsp Generic moduls on my Mac to check if it works at all. Sometimes it does but sometimes I get the info in the tsp modul that the variable $(tsp:ip_addr) is "not connected". After a reboot of the Mac it's working again.
If it is working I get the value ::ffff:127.0.0.1:49481 with different numbers at the end.
The reboot is not nice but a workaround if needed.

BUT! the same on my Raspberry PI didn't work at all. I don't get any connection between these two moduls. It always shows me the value "not connected".

Any ideas?

And please, I'm not a programmer at all. If you tell me anything to do on the Raspberry PI - tell me in simple words.
Thanks.
