I am having the same issue and I am running SODE 1.6.8 with GSX Level 2. It will keep telling me SODE unavailable when trying to position aircraft parking spots (still using P3Dv4 for that). After clicking Reload All in the SODE menu, I can get a jetway to attach to the aircraft, but a static jetway is still in the position also. After restarting Couatl and rebuilding airport cache, the static was no longer there and the jetway still attached.
After testing by connecting and then disconnecting the jetway via the GSX menu, I went back into the GSX customize airport positions and selected the same spot I just tested in but again as soon as I hit Shift+numpad 5 to test the jetway, it hesitates and then i get a SODE connection lost message and have to do the steps all over again.
I tried in a freeware update/download AFCAD to default ZGGG which GSX replaced default jetways assigned on the AFCAD, and also at FlyTampa KLAS where the 3rd party SODE jetways were kept in tact. Both fail at the same point, and again after restarting SODE and Couatl. I am not sure if this is a SODE issue or GSX issue.
I did also Just run FSDT LiveUpdate and restarted my computer. The issue still remains, however, this time when trying to edit a parking position, I got the SODE connection lost message when testing a jetway connection in the GSX customize airport positions (select the jetway and hit shift+numpad 5) and then it would tell me SODE connection lost. But without restarting SODE or Couatl, I was able to get a jet way to connect and dinconnect from the same parking position, with a duplicate static jetway still there. If I rebuild airport cache via the GSX menu, the static jetway will be removed.
