My newly installed node stopped running - see copied code below

Ok it stopped running what should i do now?
Start it again?

Looks that your node can’t syncBlock with anyone of neighbors.
Please restart nknd try again or check your neighbors what state about them.

I ran .\nknd.exe -p YOUR_WALLET_PASSWORD again and it stopped this time after much longer runtime with this code in the last page:

Again it shut down see above

Are your node is under sub-net behind firewall or NAT?
You have to setting your firewall or NAT in order to allow 30001~30003 port incoming from external internet IP.

No I created rules in the firewall to open those ports

I restarted it twice and again it shut down:

I saw this once before, it was because the router/firewall closed connections between my node and the rest of the world. I can’t really see any other reason that might cause it.

What can I do?

Tried 2 more times and it stopped again:

What does this mean “You can use -no-nat flag to bypass automatic port forwarding and set it up yourself”??

Like .\nknd.exe --no-nat -p xxx. But you would need to set up the port forwarding manually on your router.

PS: you are posting your wallet password here, please remove it for your safety

Thanks…I try to contact my ISP about this also since it’s their router

Ok I ran .\nknd.exe --no-net -p xxx and it ran for about 2 days straight then no neighbours again:

The logs shows that your node lost connections to all neighbors. This typically happens when your Internet is down (for 10s+), your IP changed, etc.

I tried installing the updated nk miner into my folder but after it all, it failed. Any ideas?

This time it seems that you don’t have config.json so nknd don’t know about seed node. Have you copied config.testnet.json to config.json?

PS: you are leaking your wallet password in your post :slight_smile:

Thanks again.

New message after renaming config.testnet.json to config.json:
