I am attempting to setup a SSL Proxy using NGINX on a Raspberry Pi 3 using the Raspbian Operating System to allow my Home Assistant application to become accessible via the internet allowing changes to be made via my mobile device.
In trying to accomplish this task I am using the following the following reference information: https://community.home-assistant.io/t/homeassistant-nginx-ssl-proxy-setup/53
I encounter issues when I am trying to obtain a new certificate (using the command ./letsencrypt-auto certonly --standalone). This command will prompt me to enter my domain (hosting provided is namecheap) which I enter http://www.wiinc.tech/, I have also tried the following variations:
I receive the following error from using www.wiinc.tech:
Failed authorization procedure. www.wiinc.tech (tls-sni-01): urn:acme:error:connection :: The server could not connect to the client to verify the domain :: Failed to connect to 188.8.131.52:443 for TLS-SNI-01 challenge
I’m not sure how to resolve this error or further triage what could be the cause the failure to connect.
Any help would be greatly appreciated.
