Connection timeout


Recommended Posts


I got my Windows 10 laptop re-installed, and now I cannot get Synergy to work.

* Server: Ubuntu 18.04, Synergy 1.8.8

* Client: Windows 10, Synergy 1.8.8

I've verified with netstat that port 24800 is open and listening. On my Windows laptop I've tested the socket using PowerShell / Test-NetConnection - the socket works, and I see inbound connections on the Ubuntu side when using this. However, when I try to start the Synergy client, I see that it's attempting to connect to the correctly resolved IP address and port 24800, but I get "Timed out" for every attempt.

I've verified that Synergy is in the app whitelist for Windows Firewall, with access to domain/private/public networks.

How can I debug this further? I guess it's a client side issue since I am able to send TCP packages from Test-NetConnection but Synergy Client does not connect.

Also tried synergyc from the command line with DEBUG2 log level and can't really see anything from there:

@HenrikH a couple of things to check:

1. Both computers are in the same network/subnet?

2. No VPN on your server?

3. Make sure to check if the server network type is set to private.

Let me know if this helps.
