Thank you very much. I've identified the problem; it was a bug in ACSRelay. I'll upload a new version soon™.

Hey @Coret3x! Just taking a break from RL, did you manage to pinpoint your issue to ACSRelay? I see there were some changes in the protocol for AC v1.7, but ACSRelay should still work. I will release an updated version of ACSRelay soon(tm), but I'm not sure I can help you. Can you give me more details about your problem?
I'm using this too, Stracker join messages work. But lap statistics are not working, is anyone else experiencing this problem? Are there any reliable alternatives to ACS Relay?
