If you're running your node from 2017 on, it could also simply be that there's no space left on the storage device. Do you operate a full or a pruned node? How much free space is on the device that stores your Bitcoin Core files? Running out of space should produce some other debug.log entries, though than this port mapping issue.

I'm not sure if

Code:

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

is the terminating error, even when it shows up multiple times in your debug.log file.

What is written as fatal error indication in your debug.log when Bitcoin Core terminates?

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 ??

Just in case, do you see any other error / warning message? If you're not sure, you could try share content of debug.log either here or website such as Pastebin.

Hi and thanks for your answer,

I used to be under v25, i just tried to upgrade to v27 but it did not work, same message...

Does the error still appear when you add the line to bitcoin.conf? It should be an error that is associated with upnp instead of Bitcoin Core. Is the portmapping error the final line before Bitcoin Core closes?

AddPortMapping should be related to UPNP in Bitcoin Core, you can try to disable UPNP by putting this line into your bitcoin.conf:

Code:

upnp=0

What version are you using? If your version is far too old, I'd suggest you to also upgrade your Bitcoin Core since upnp is disabled by default for a while now.

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
