Can’t connect to Win server 2016 remotely from specific devices, (this computer can’t connect to the remote computer)

remote desktopwindows 10windows-server-2016

We have an online Windows server 2016 that we connect to from several locations(from outside and inside the office)remotely using the native remote desktop software in our machines, we are using windows 10 with latest updates and every thing is just working fine.

When I try to connect to the server from my home, it wouldn't connect at all, I have tried several machines (physical and virtual)with several windows 10 versions(pro~enterprise) and I always get one of two massages

This computer can't connect to the remote computer. Try to connecting
again. if the problem …..

or

An internal error occurred ….

The remote desktop window always stuck at "Configuring remote session…" before giving the error messages

I made sure the RDP port is opened from my side to the server by using 

Telnet server_ip 3389

This issue only happens to me but not to my colleagues, they can connect from their homes and even from other countries!
I have a private (connected directly to the DSL router without anyone else) DSL connection to my house by the way.
I have tried a lot of solutions, wasted a lot of time trying to fix this issue but failed!
