#12558: Tor doesn't show warning for non-reachable IPv6 OR port

 I recently upgraded my routers firmware. After that, I restarted Tor as
 usual. After one day, I noticed that atlas is showing my relay as offline
 since restart.

 After more than hour of investigating, I found out that my router gave my
 Raspberry Pi a new IPv6 interface ID. Due to this, my port forwarding
 didn't work anymore.

 The strange thing is: In my tor logs, I saw this:

 "Self-testing indicates your ORPort is reachable from the outside.
 Excellent. Publishing server descriptor."

 Looks like Tor was just referring to my IPv4 OR Port, which was still
 reachable, and didn't notice my non-reachable IPv6 OR Port. This issue
 should be fixed.
