Hi there, You seem to be running the following Tor bridge, which is great: 4290EEF4276FEACAD3A4694770B3B905FED51302 But that Tor version (0.4.0.4-rc) is obsolete, and because of old bugs, we will soon cut bridges running those versions out of the network. Please consider upgrading! You can find Tor packages and instructions for your distro / OS here: <https://community.torproject.org/relay/setup/bridge/> Ideally you will switch to keeping up with our stable releases, but if you need a stable that is especially stable, the Tor 0.3.5 branch will be maintained until Feb 2022: <https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/CoreTorReleases#Current> and you can see the lifetimes of other Tor versions on that table too. Let us know if we can do anything to make the process easier. And lastly, I am copying the new network health mailing list (which has public archives), to help us stay synced: <https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkHealthTeam> Thanks, Philipp
