ERR_SSL_PROTOCOL_ERROR on custom domain

Help
,
1

Current:
Website runs on localhost:3000
Website runs on <random-words>.vercel.app
Receive ERR_SSL_PROTOCOL_ERROR when accessing website through custom domain on any device

Expected:
Website should run on custom domain without any SSL errors on any device

I followed this tutorial exactly step by step to add the A and CNAME records for my purchased domain: https://www.youtube.com/watch?v=ZnZG7_W6yGE

Don’t know if this helps, but 2 of the checkers on this website claim my domain has malware: https://www.urlvoid.com/ , The .vercel.app domain has no problems.

I would prefer to not share the domain of my website, but this is a breakdown of the website that might be of help:

  • website displays images that are stored locally in my GitHub repo
  • I am using <img/> instead of next/image
  • Only user interaction is clicking on buttons to navigate between subpages and one input field that adds a query param to the URL
  • There are no redirects to outside of the domain

Hi, @nicklitvin! Welcome to the Vercel Community :smile:

Could you follow the following guide?

Visiting the website using mobile data or from a different region of the country fixes the issue. It looks like my ISP blocked my domain even though the vercel domain contains the same contents but works fine. The ISP refused to unblock my website so I might try contacting namecheap (from whom I purchased the domain) regarding this as I don’t think this is a problem with my website.
