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.
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 184.108.40.206:443 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.
Your “domain”, hosted at namecheap. Is that just the domain or is your entire website hosted on a VPS or shared hosting environment there? Because I can see some Namecheap placeholder if I surf to your domain, so I’m pretty sure your domain name doesn’t “point” to your Raspberry Pi.
