I just changed internet providers. ATT to Spectrum. They provided a router. I opened port 8123. Have been using duckdns to get to my home assistant which is running on a a ubuntu 18.04 server running docker. When I try to start the ducksdns container I get the following error.
ERROR: Problem connecting to server (get for https://acme-v02.api.letsencrypt.org/directory; curl returned with 6)
I have searched the forums and found discussions pertaining to the DNS server used by some isp’s. I did install resolv.conf with dns address’s 8.8.8.8, 8.8.4.4 but still get the same error.
I suspect the problem is in the Specturm router so ordered a new router that I can configure myself.
I anyone knows a way to resolve this without installing a new router I would appreciate help.
Thanks
