Hello ppeixoto,

There may be a lot of issues causes that you received 138 error (ERR_NETWORK _ACCESS_DENIED) while connecting. All are related to network configuration. To check where a problem is, please go through following steps:

– Check if your external IP on server host is the same like indicated by NoMachine Client (Server Status window from your screen). You can check it for example on https://www.whatismyip.com/.

– Check if you can ping external IP of your server host from your client host.

– Check on router if ports which you use to connect using NoMachine isn’t blocked.

If your server is behind a NAT router or a firewall it’s possible that you have no UPnP enabled on your server side router. In that case please follow https://www.nomachine.com/AR11L00827 article.

 

Regards.

Hello Nars

Thanks for the help. I checked your suggestion and the IP has correct but i couldn’t ping the remote machine.  That isn’t related with the NoMachine but can you please suggest some possible errors or configurations that i need to do to be able to ping my remote machine ?

Thanks

Without knowledge about your network environment it’s very hard to say.

You could:

– Talk with your ISP, ask if you have individual external IP

– Check if pings are blocked in your router settings

– Scan if you have ports used by NoMachine blocked (ex. using this http://www.ipfingerprints.com/portscan.php page)

 

This kind issues you should solve with your administrator or network provider 🙂
