udp Error - dl4fcj - 04-03-2026
Hello everyone, I've encountered a new bug in Swisslog V 5.115. The connection to Swisslog via UDP is no longer working. The error message is: 10057 socket is not connected. The error occurs with both WSJT and JTDX. The settings seem to be correct. Something must be misconfigured, but I can't find it! I'm hoping for a tip! 73 de Lutz DL4FCJ

Hi Lutz,
Swisslog has no problem but your configuration. In Swisslog disable the Forwarding. Forwarding is intended to do it in ANOTHER port different than 2237 (main). You are forwarding to the source port and this is causing your issue. By default this is not defined this way so you have had to change this manually. I suggest to read this chapter where all these settings are explained:
