Problems & how to fix them

/.well-known/matrix/server could not be reached over [2a02:247a:263:5300::1]:443

[2a02:247a:263:5300::1]:443 specifically didn't answer, even though the well-known file (and the rest of federation) may work fine over this server's other addresses. That's a real, address-specific reachability gap on the server's own network: any other homeserver trying to federate over exactly this address will see the same failure, regardless of which server is asking. This address itself needs fixing on the server side, other resolved addresses for this server aren't affected.
