SSTP VPN connection terminated in 10 seconds while entering credentials (on Windows native client)
Posted: Wed May 12, 2021 7:40 pm
Hello!
I noticed a strange behavior while connecting to SSTP VPN using Windows 10 native client: after credentials pop-up appears, the connection is being terminated in 10 seconds with error "A connection to the remote computer could not be established, so the port used for this connection was closed".
However, if I submit credentials within 10 seconds or credentials are already saved, the connection works as expected.
Server logs (Oracle Linux Server release 7.8):
Also I ran Wireshark on Windows client machine and found out that the server sends TCP RST packet that causes connection termination. So I believe that the problem is on the server side.
Is there any kind of time-out that can be configured? Thanks!
