Hi there,

I’m running into a problem similar to @nebeleben, I think. I’m stuck at the creation of the ID.

And if I wait, the last line outputs again every couple of minutes.

This line catches my attention:

Error creating new order :: too many certificates already issued for: nknlabs.io: see https://letsencrypt.org/docs/rate-limits/

But I’ve tried this command multiple times, so perhaps I have exceeded the limit for my IP address.

@nebeleben was suggested to generate the ID on a separate machine. Do you also think I have to do that? I would prefer not to, since I have no idea how - I would need a full tutorial for that.

#25

Update:

I’ve managed to run nknd from my Mac using the same wallet.json file I had in the Raspberry Pi. ID generation is then successful, yay!

But… when I copy that wallet back to the Raspberry and run nknd there, it fails again. :frowning:

It give me:

[INFO ] GID 1, GetID got resp: {"error":{"code":-45022,"data":null,"message":"INTERNAL ERROR, there is no ID in account"},"id":"1","jsonrpc":"2.0"} from http://mainnet-seed-0040.nkn.org:30003

At that same point, my Mac gets this instead:

[INFO ] GID 1, GetID got resp: {"id":"1","jsonrpc":"2.0","result":{"id":"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"}} from http://mainnet-seed-0021.nkn.org:30003

And is able to continue. Any ideas @yilun or @zbruceli?

#26

This is quite strange. Are you sure you are using the same wallet.json on both side? And they are both in your current working directory when you start nknd?

#27

Ouch! I had a different wallet on the Raspi. My bad. I was convinced I synced the wallets in the two devices, but I must have missed something in the process.

Now it seems to be running the node. Or at least trying to! I see a lot of lines like:

Ping ... error: Wait for reply timeout
Error sending sync messge to node
Get consensus state from neighbor ... error: Wait for reply timeout

and only every now and then also

DropTxns: X txns (XXX bytes) in txpool, no need to drop

Is that normal?

#28

OK, after fiddling with the router config, I’m getting better results. Turns out removing my manually added Port Forwarding rules works better. Now the raspi/router adds the rules as “Automatically added by UPnP” and the node seems to have more successful connections. Now I’m getting many more of these lines:

Remote node connect from xx.xx.xx.xx:41322 to local address xx.xx.xx.xx:30001

Still I’m getting an overwhelming amount of errors like the ones I mentioned above in between. Is that normal?

#29

All of the logs you mentioned are normal. The default log level is pretty verbose, just in case you need some info to debug :slight_smile:

So, my Raspberry Pi seems to have been mining for almost 24 hours, however nStatus still says “node offline.” NKNx on the other hand took very long to start listing the node, and when it did, it has it under “WAIT_FOR_SYNCING.” Is that also normal?

#31

That typically means your port forwarding is not set up correctly on your router.

PS: currently nknx is not updating node status and they are working on it. Check their pinned msg in #nknx channel in discord for more info.

Turns out it is super important to upgrade the version of GO. Only after downloading and extracting the latest tar ball did the compilation work. Thank you for this.
