Timeout while connecting to the selected mirror.

Hi I have problem with updates. If I select any update server from list, always I get error message
Timeout while connecting to the selected mirror.

Can you help me? Internet connection is working properly. Actually I have 20.1 build, OpenSSL, branch Production. I tried Deciso, Aalborg, dns-root.de and many others, but without success.

I had the same issue that you describe. I noticed that I was able to update and install packages when connecting through SSH, though. It would simply take forever, i.e. multiple minutes.

The cause was a configured but faulty IPv6 address on the WAN interface. To fix the issue, simply disable IPv6 on the WAN interface. The IPv6 timeout seems to be set very high, without an easy fallback solution (cf. Happy Eyeballs algorithm).

Note that in my setup the OPNsense firewall was running behind an ISP provided router that had 6rd configured.

I'll try that. Thanks a lot :)

It works, great.
