LetsEncrypt Error in nkn-commercial

Nodes & Mining
#1

When tailing the nkn-commercial logs I noticed the following errors in the logs. Is this of concern and does it impact mining :

2021/04/14 18:03:55.075170 [ERROR] GID 64, apply cert failed: acme: error: 429 :: POST :: https://acme-v02.api.lets

Also, should the HTTP(80) and HTTPS (443) ports for miners be open or firewalled?

Thank you.

I am also getting the same errors. Any help would be appreciated.

I was able to resolve this issue by forwarding HTTP and HTTPS port 80 manually and by running mining node as a ROOT user.

Hello , can I do this also with windows pc? How to port forward?

NKN UPnP

NKN Port forwarding

Port forwarding for ports 30001 to 30005 is done automatically. You can check this by logging into the router and then go to UPnP configuration. You should be able to see forwarded ports.

I had to do manual configuration for forwarding port 80. For this, I went to Forward Rules => Port Mapping Configuration and created new mapping as shown in the above screenshots. I created a mapping for both HTTP nd HTTPS.

Thank you. I think this will help others with the same problem.

In my router, I already port forwarded ports 30000-30021.

My only problem is, I don’t what to do with port 80.
