[tor-relays] Bridge showing offline

[Eddie]

Looking at tor metrics, one of my bridges is showing as off-line: 
B080140DC1BAB5B86D1CE5A4CA2EF64F20282440

However, the log isn't showing any issues:

Initially I thought of a previous issue I had with IPv6 connectivity, 
but don't think this is the problem here as the 2nd bridge on the same 
server is showing on-line.  Also an IPv6 port scan shows the ports for 
both bridges as accessible.

Ideas ??

Cheers.
