Hello,
I received the error again today, using the FSLabs A321, and again it occurred the second I switched off the beacon light, which should initiate the connection of the jetway. All other events with the FSLabs A320 and A321 are working with GSX using the inbuilt functons on the aircraft, and I have never seen this issue apart from when I switch the beacon light off in the A320 or A321. I ran Live Update today before I started the flight, but it made no difference.
I had a quick look at the coautl log and it seems it has only recorded the events after the error, as I restarted couatl and GSX when prompted and connected the jetway manually and requested deboarding.
Please find the log file attached.
Thanks,
