Failed to connect to the server due to network error

Hello all,
I have a problem that when I turn On my server’s VPN, an error of code 48 comes out with a message " Failed to connect to the server due to network error. ", anyone faced that before?

NOTE: everything works fine when VPN is Off & I am using Ubuntu 20.04

Hi Ibrahim,

Please use the following link to download the Network tool and share the console logs on support@cryptlex.com.

I am trying to execute the file in my docker container, but I always get: : cannot execute binary file

What is the base image of your docker container?

it is : node:14.15.4-alpine

We have now included a network tool for alpine distribution as well. You can now download the latest network tool from the link below:

now that’s the response I got.

It seems that the outbound network requests are blocked for this machine and it may be due to a firewall. Can you please confirm that?

Thanks a lot for this tool, THE Issue was in firewall and SOLVED.
