Quoting Dionysios K. via tor-relays (2024-04-25 05:00:14)
The issue was solved for a few hours, it was the first time since I switched to webtunnel I saw my bridge online, but now it's again marked as offline.
The problem got temporary resolved by restarting bridgestrap, but it looks like there is a bug somewhere where bridgestrap stops reporting metrics: https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/issues/199
This bug doesn't affect the distribution of the bridges, but the reporting on the metrics side. You can see the information that rdsys has on your bridge, like if is functional and/or it's bandwidth good enough in: https://bridges.torproject.org/status?id=<bridge-hash-fingerprint>
