I followed this guide to set up a Matrix server on my Pi. The only hiccup I ran into during setup was under “Setting up Synapse server,” step 11, the “Registration” section wasn’t present in homeserver.yaml. This server is meant to just run bridges to WhatsApp/Facebook/etc. so I wasn’t too worried, and forged ahead.

I’m getting the title error when trying to connect via Element. Federation Tester gives the following error:

Get “https://[my ipv6 address]:8448/_matrix/key/v2/server”: dial tcp [my ipv6 address]:8448: i/o timeout (Client.Timeout exceeded while awaiting headers)

Any help would be very much appreciated.
