Hi everyone,

Back from 2017 and still in love with Bitcoin, I'm running a full node on my computer since 2017...
Unfortunately, i'm not a "software pro" and the BitcoinCore is not able to open anymore for the last 2 or 3 weeks.
I've got this message :

"a fatal error occurred, see debug.log for details" .
 
In this file i have very often that :

AddPortMapping(8333, 8333, XXX.XXX.X.XXX) failed with code 718 (ConflictInMappingEntry)

Any advise ??

Thanks a lot
