Hej,
they are all green again on metrics ;)
Your bridges showing offline from time to time is related to not exposing your ORPort (which is highly recommended). See these 2 tickets:
https://gitlab.torproject.org/tpo/anti-censorship/team/-/issues/129 https://gitlab.torproject.org/tpo/web/community/-/issues/329
If you can use your bridge and its shown as “webtunnel: functional” when you check here: https://bridges.torproject.org/status?id=$YOURFINGERPRINT everything should be fine.
Best regards, atari
