Do you run this on a hosted VPS or at home?

Betreff: [tor-relays] Tor [] {Bridge} IPv4 not found


Hey, I'm running Tor [] on Ubuntu 20.04.2 LTS and started running my first bridge following the exact tutorials on the community guide for running bridge. However, the syslog says(resulting in non-reachability of the port.):


Tor[6278]: Unable to find IPv4 address for ORPort 11120. You might want to specify IPv6Only to it or set an explicit address or set Address.


Here's my torrc conf:


BridgeRelay 1
ORPort 11120 IPv4Only
ServerTransportPlugin obfs4 exec /usr/bin/obfs4proxy
ServerTransportListenAddr obfs4 <>  IPv4Only
ExtORPort auto
Nickname dubridge



Steps done:


Saw the router configuration (IPv6 disabled in there).

Thought maybe some issue with dynamic/static IP so configured DHCP ADDRESS RESERVATION to get a static IP.

Followed a similar thread on this topic by a guy recently so wrote IPv4Only in front of both ORPort and obfs4
