Great question. I know my ln address is different to different people.

I'm trying to debug the same issue.
Idk but you can probably make one pretty easily.
I made this a little while ago as I was getting zaps to an old address, but just pushed up some changes. It's just a python script that queries all queries all online relays, identifies relays with old events, rebroadcasts the latest verified kind 0 event to those relays and reports the status of the rebroadcast.
Going to update it to make it a bot so people can update by DM'ing it
