Connection timeout

[Florent433]

Hello everyone,

I am trying to get remote access to a Viglen Genie VIG830S remotely from my MacBook Pro and it was working fine for a couple days until I get the following message since yesterday:

“A connection timeout has occurred while trying to connect to ‘nocs-desktop.ddns.net’ on port ‘4000’. The issue could either be caused by a networking problem, by a firewall or NAT blocking incoming traffic or by a wrong server address. Please verify your configuration and try again.”

I am connected to a GlobalProtect VPN as this is a University based computer.

I am attaching the logs for the NoMachine and the GlobalProtect VPN.

Does anyone has a solution?

Many thanks,

Florent Fayolle

Hi,

Could you please send the logs via email? You can gather both player and server side logs by following the instructions in https://kb.nomachine.com/DT07S00243. You can send the logs to forum[at]nomachine[dot]com.

Hello,

I have followed the instructions on the link you gave me to collect both the play and server side logs but it’s giving me the following error message when running the command line for the first step:

NX> 500 ERROR: Cannot enable debug mode for: server.

NX> 500 ERROR: Cannot open file /Applications/NoMachine.app/Contents/Frameworks/etc/server.cfg.tmp

NX> 500 ERROR: Operation not permitted.

Also, this morning, I managed to connect remotely somehow, but it suddenly froze and am now getting the same message as in my previous post. It looks like its working for a limited amount of time.

Any help would be great.

Thanks.

Hello,

I have sent my logs last Thursday to you by email, as requested, but haven’t heard back from you on the issue.

Could someone help me?

I still haven’t been able to fix the problem.

Many thanks,
Florent

Hi Florent, we have received them and they will be analyzed by our developers soon.

The logs you sent were from the Mac client you are connecting from. We would need to see the server side logs as well. In any case, it seems to be a networking/configuration problem on the server side, with the IP address possibly being dynamic (so it has changed since you last connected?) I noticed the domain you are connecting to. If you are not the administrator of the computer you are connecting to, are you able to contact the administrator of the organization’s NoMachine server? Something must have changed at the network or configuration level of the NoMachine server you are connecting to. If you are the owner of the server machine and can access it, send us the server logs as well. Please also see this article here:
