Intermitted LG failure connecting to Saas Performance Center

Hello
I'm hoping you can help me resolve the following errors. I'm getting these intermittently, and they cause any test running to fall over, and I need to reboot the load generator host from Performance Center, before I can resume.

I have executed the same test at different times, so I believe my scenario is OK. I just cannot seem to find any relevant reason or solution as to why these errors occur, and I therfore don't know how to resolve.

We have other load generators, that are connection OK to the Saas environment, and they run the same versions, and we do not encounter these issues.

Any guidance you could provide would be appreciated.
