I have a 2 dual boot machine and NoMachine has always worked correctly on linux and I never had a problem connecting from Linux although I have had problems sending Control characters on occasion. Its the Windows 10 machine which wouldn’t connect. On investigating further I determined it was a profile problem as I was able to successfully connect from another login on the machine. What help you all can give me would be how to diagnose such profile problems as I am clueless. Somehow on this profile the log did not write and expect some permissions problem.
