Tried editing Group Policies as well, using GPE(Group Policy Editor). Disabling the firewall does make the issue go away. Īdding a new firewall rule in windows firewall for putty, didn't help, since the connection is not blocked, just that delay.Īlso, for testing, trying to find offending rule, I simply disabled all of the active firewall rules, no change, the same 20 second delay. Initially, I suspected server config, tried all the common solutions, UseDNS is set to no, and to summarize, none of the resolutions listed here help. Enabling/Disabling VPN on both server/win11 client has no effect, same delay, while Android connects fine with VPN on both server/client or no VPN.SSH port number is irrelevant, same issue on 22 or any other.

Two different android clients from two different devices connect to the same server/port without any issues or delays.Delay is the same for password or keyfile connections.However, the same clients connect to WAN server with no delays.Win11 ssh clients: putty, WSL2 ssh, both experience 20 second delay when connecting to the server on LAN.My local server is running Ubuntu 22.04.The problem appeared once I upgraded my dev computer to Win11, which was running Win10 before that.
