Full node is not working anymore after power outage

[dragospirvu75]

Hello! Full node is not working anymore after the power has been turned off suddenly (I didn't have time to close Bitcoin Core).
Now, Bitcoin Core opens normally, but my full node doesn't work anymore (I checked it on bitnodes.io)

Any ideas on how to fix it? Thank you!

I'd start by checking port forwarding, for instance from router settings.

I will try tomorrow because right now I'm working at a project that needs to be finished in 1 hour and a half and after I will go to sleep. Thank you for your suggestion of checking port forwarding and if anyone has another ideas, tell me. Thanks!

What operation system you are using for full node, Linux, Mac or wiNd0ws?
This is not the first time I see something like this and some files probably got corrupted when power went off suddenly.
Try restarting everything manually and try to reindex the blocks again, if that doesn't work you may need to download blockchain all over again.
Best protection against this would be getting some UPS or running your node on laptop with battery as backup.

I'm using windows 10 on my pc. I've read that files could get corrupted in case of sudden close, I hope this isn't my case but I'm prepared.
I will try and restart everything, I hope it will work. And yeah, I will consider a UPS or laptop. Thank you very much for your advice!

Check the log. In Windows, it should be in C:\Users\<USERNAME>\Appdata\Roaming\Bitcoin\debug.log if you haven't specified its location. The case with power outages is common, it has happened to me before too[1]. I think I got away with it with only a Bitcoin Core restart.

Mostly corruption is the cause if you didn't close the bitcoin core properly.

The only solution that I know to fix the issue of Bitcoin core corruption is by using -reindex since you are using Windows OS you can put the -reindex in bitcoin core shortcuts under target: just like this image below then apply. Relaunch the Bitcoin core and it should start reindexing.
