Connection problem

[Concetta]

Hello to everyone,

I’m struggling to connect my Windows laptop to my Mac (at the university) by using the VPN.

The connection was working one month ago (I was connecting using HTTP proxy) and I was able to connect remotely from home to my Mac by using the software NoMachine.

Now I’m experiencing some problems: although I think I am connected to the Palo Alto VPN client, the server is not responding when I try to connect to the Mac.

 

I always have this error:

Could not connect to the server.

Error is 138: Connection timed out.

 

I don’t understand what it is going on and why the connection is not working anymore (even if it was working some time ago).

 

I am suspecting this is a problem of the NoMachine software because I am able to connect to the Mac with TeamViewer.

Are you sure that you are trying to connect using the correct IP? Can you ping the server machine from the Windows machine and see the result? If you are sure that the VPN settings are okay and you can reach the host for example through SSH using PuTTY, please verify if nxserver is started on this Mac and if it is possible to connect there locally via NoMachine.

If problem still appears, please send the logs from client and server sides to forum[at]nomachine[dot]com. Before, make sure to enable debug on Mac and restart nxserver (sudo /etc/NX/nxserver --restart). Instructions about debug and collecting logs can be found here: https://www.nomachine.com/DT07M00098.

Hi kroy,

Thank you for your reply.

I was able to fix the error.

I leave here how the problem was solved in case other people have the same trouble.

There was an issue with the firewall policy of the university and it was solved by the IT Service Desk of the University that amended the policy.
