Hey, I'm running Tor [0.4.5.7] 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 0.0.0.0:356 IPv4Only
ExtORPort auto
ContactInfo __REDACTED_FOR_PRIVACY__
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

Thanks!
Someone
