Anything I can do about connection drop-off?

I’ve been running a bridge since May 2018 with the following config:

BridgeRelay 1
ORPort 8101
ServerTransportPlugin obfs4 exec /usr/bin/obfs4proxy
ServerTransportListenAddr obfs4
ExtORPort auto

According to, it’s been running at about 15 connected clients with a sudden spike between about 2020-04 and 2020-09 (up to 60 for a while), then again 2021-12 and 2022-02 up to about 40, whereupon it sank down to about 10 per day and falling.

Is this latest collapse a Russian thing? I see it says it’s blocked in RU. Should I try tweaking the config? I can’t change the IP address, unfortunately.
