20.1 Legacy Series / Re: Timeout while connecting to the selected mirror.
« on: February 16, 2020, 04:07:35 pm »
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.
