I got an error with “Error is 138: Connection timed out”. I did the following test. 1. I can connect to the desktop using Remote Desktop Connection from the laptop. I think the IP and the desktop is fine for connection. 2. Then I tried the connection to the desktop from another laptop which running NoMachine with the same version. It works with the new laptop. So I think the connection to the desktop is no problem with the desktop. The problem may come from the 1st laptop. 3. I checked the fire wall of the 1st laptop and I found that NoMachine is allowed. I stopped the real time protection. I still can’t connect to the desktop with the 1st laptop. I don’t know what I can do to fix the connection problem for the 1st laptop. Could you please help with this? Best regards This topic was modified 7 years, 11 months ago by Britgirl.

I may reinstall the 2nd laptop in the worst case. Author Posts Viewing 3 posts - 1 through 3 (of 3 total) This topic was marked as closed, you can't post.
