"Managed proxy at '/usr/local/sbin/webtunnel-server' failed the configuration protocol and will be destroyed."
A bridge operator reported that their WebTunnel bridge stopped to work and found this message in their logs:"Managed proxy at '/usr/local/sbin/webtunnel-server' failed the configuration protocol and will be destroyed".
After restarting Tor, the bridge went back, but today it stopped again. Any ideas on why the webtunnel-server has crashed? Which logs they should provide for further analysis?
