Error is 138: Connection timed out

[othplay]

NoMachine Version – 4.2.26

I try to connect from one laptop with Windows 7 enterprise to one desktop with windows 7 enterprise. 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

Are you able to connect from the PC (the desktop you were trying to reach) to the first laptop?

Thank you for your reply.

I still can’t connect to the desktop from the 1st laptop.

But I can connect to the desktop from the 2nd laptop.

I may reinstall the 2nd laptop in the worst case.
