[VIPM on Linux problem]

Hi,

I have LabVIEW Linux 2020.0.1 64-bit on Linux Mint 20.1.

I installed VIPM 2017.0.0f1 according to the instructions with no problem, but when I want to verify the connection, I have this error in the log file :

Could not connect to LabVIEW 2020 (64-bit) on TCP/IP port 3369, because LabVIEW 2020 is already running and using that port. Please close LabVIEW 2020 and try again.

I tested every solution on VIPM website and forums but doesn't work.

Full log file content:

Possible reason(s):
