Describe the problem/error/question

I have installed https://www.npmjs.com/package/n8n-nodes-portainer community node. Cannot save portainer node account - it constantly says Invalid URL. I have 3 ports opened - 8000, 9000, 9443 0 tried all of them - none works. The IP is 172.17.0.1 since n8n is running inside docker bridge network.

What is the error message (if any)?

Cannot save the account because “Invalid URL”

hello @ndrewpj

Two issues may be there:

  1. You need a domain name instead of an IP, as usually HTTPS requests over an IP address won’t work due to the SSL certificate issue

  2. IP of x.x.0.1 is usually used by the gateway

I tried the FQDN name too. I have self-signed certificate, some nodes have the “Ignore SSL errors” switch which could be handy here too. Ah, I guess I’ll have to use the HTTP node. It is a pitty, this portainer node is so nice

You can disable the SSL check globally, but I do not recommend doing so in Production:

set the ENV NODE_TLS_REJECT_UNAUTHORIZED=0
