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.

jubilee · May 31, 2019, 5:36am

No I created rules in the firewall to open those ports

jubilee · May 31, 2019, 5:37am

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.

jubilee · May 31, 2019, 9:17pm

What can I do?

jubilee · June 1, 2019, 6:48am

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”??

yilun · June 1, 2019, 4:02am

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

jubilee · June 1, 2019, 6:49am

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

jubilee · June 7, 2019, 6:30am

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.

jubilee · June 15, 2019, 3:14am

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

jubilee · June 15, 2019, 3:31am

Thanks again.

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

How to setup these settings in firewall. I got the same issue but don’t know how to add it in firewall.

zbruceli · October 12, 2019, 4:56pm

It depends on your firewall, so it is difficult to pinpoint which menu to use. But in principle, to enable port forwarding on ports 30001, 30002, 30003 (both TCP and UDP) on your WiFi home router.

hakimchi · October 21, 2019, 5:56am

Hello Leader,

I’m getting the same error as Warning: Local node has no inbound neighbor, it’s possible that local node is unreachable from outside, e.g. behind firewall or NAT.
As per your instruction i open my router but in the port formwarding which option i should choose to give the port address. External port or Internal port. I’m still mining this is my first mining experience in my laptop but after mining for some hours no bonus credited to my wallet. My question is - How long i have to mine to get 1 NKN in laptop and can i trade the mined NKN coin in exchanges.

Thank you

zbruceli · October 21, 2019, 4:12pm

Hi, in your router configuration, please configure “port forwarding” for TCP and UDP 30001, 30002, 30003.

On average, each node can mine 2 NKN per day. But the mining reward comes in blocks of 11.42 NKN, so average one node can get one block reward every 5-6 days. But this is average over long time and across all the 22K nodes. You node might be lucky or unlucky, since the average is statistical, not guaranteed.

hakimchi · October 22, 2019, 1:19am

I think if I’m unlucky then better to buy NKN in exchange rather then mining for 5 to 6 days and get nothing. Thanks leader for your response. Becuase i think mining is good for game PC’s not laptop’s.
