I tried this route because the “Official” DDNS addon for Hassio is not working for me.
When I try to start the DDNS service I get this error
Generating account key…
Registering account key with ACME server…
ERROR: Problem connecting to server (post for https://acme-v01.api.letsencrypt.org/acme/new-reg; curl returned with 52)
Did you get any resolution to this? I’m having issue that none of my addons can get any data thru https connection. Http works fine but https results same error that you posted “connection reset by peer”. For me it’s atleast for Node-Red and SSH addons.
Any info on this error?
