I have Node Red running on a Raspberry Pi 3B+. I have set up https certification with acme.sh, zerossl and duckdns. Everything is OK in the settings file, and when starting it says in log file that it is listening on 127.0.0.1:1880. I have port forwarded the ports 22 and 1880 to my pi, with a static dchp ip, in my router, and I can connect to the node red instance using the dedicated dns within my local network, but once I go anywhere else, I cannot connect to mydns.com:1880. But I can open an ssh connection to mydns.com:22, is there anything I am doing wrong with node-red?
So I can connect to my pi externally using port 22, but not 1880, why? Is it something I have missed in node red?
Appreciate all answers!
I believe there is something wrong with node-red settings, or something that points to the dns address/node-red instance. If I remove the https config in settings, I can once again log in externally. But it does not work with https, although the certificate works, and is correct. I do not get any error in the logs either. Tried to set up a secondary dns to node red instance, and made it work, but got a message that the https certificate belongs to my first dns address…
Another discovery: I can connect on the original dns, only if I remove requirehttps from the settings. Which means I will not be able to connect with https…
Talking to yourself really makes you think. Figured it out. Had to set requireHttps to false, and then connect using https//:mydns.com:1880. That is the only way it works, cannot connect using only http connection.
