[tor-relays] Tor is reporting my bridges as offline

Hi, I run 2 bridges on a hosted VPS.  Tor is currently showing both these as offline for the last hour or so, but I can still connect to them from a Tor Browser and looking at the local logs, they are both running quite happily. Any ideas why they are showing as offline: https://metrics.torproject.org/rs.html#search/OhNoAnother Cheers.
