When you're setting up a custom domain on Dub.co, you might run into some issues. Here are some common ones:

domain.com redirected you too many times (ERR_TOO_MANY_REDIRECTS)

Browser error message saying 'dub.engineering redirected you too many times'
Browser error message saying 'dub.engineering redirected you too many times'

If you're getting a domain.com redirected you too many times error in your browser, chances are you're using Cloudflare for your domain hosting and are missing an extra configuration step to make this work.

To fix this, all you have to do is either:

  1. Set your SSL/TLS settings to "Full" (if you're using Cloudflare's Proxy)
  2. Use Cloudflare DNS only (without Cloudflare Proxy)

This site can't provide a secure connection (ERR_SSL_PROTOCOL_ERROR)

Browser error message saying 'This site can't provide a secure connection'
Browser error message saying 'This site can't provide a secure connection'

Another common error is when the https version of your domain doesn't work (but the http version does). When that happens, you'll get a This site can't provide a secure connection error in your browser.

The reason for this error is that the SSL certificate for your domain has not been generated yet, and it should automatically be resolved anywhere between 1 to 24 hours. If your domain still doesn't work after 24 hours, please send us an email and we'll be happy to help you out.
