Hello

I was working with “CPANEL-GODaddy-letsencrypt” and everything was fine, SSL worked perfectly for a website of mine.

I then had to install Tailscale on it for internal security mostly for ssh - port 22 access. The letsencrypt SSL did not work for a new wesbsite, it did gave the following error “HTTP DCV error, Timeout during connect”

Any directions?

Thank You.

Hello

This looks like a cPanel AutoSSL / Let’s Encrypt HTTP DCV issue.

cPanel says this error usually means Let’s Encrypt cannot reach the site on TCP port 80:

Let’s Encrypt HTTP-01 validation also requires public port 80:

Please check DNS, firewall/routing, and whether installing Tailscale changed public access to port 80.

You may also want to check AutoSSL logs in WHM:
