Hi,
I have a similar case when debugging on remote sites (USA or Asia from Europe). In my case, it takes 15 to 30minutes to get the control on the remote application. I opened a thread on NI forum but the answer wasn't satifying (https://forums.ni.com/t5/LabVIEW/Slow-remote-debug/m-p/3751311). Maybe in your case would it speed up the debug process.
Best regards
Jean-Daniel
