I’m seeing the net::ERR_CERT_COMMON_NAME_INVALID error. Has the Korean ISP blocked the vercel.app domain?
Not only is my website affected, but I am also unable to access other websites with the same issue. Could this be related to the SSL certificate or another configuration?
The domain troubleshooting guide can help with most custom domain configuration issues. You might be able to use that guide to solve it before a human is available to help you. Then you can come back here and share the answer for bonus points.
You can also use v0 to narrow down the possibilities.
Hi, Lee! Welcome to the Vercel Community 
Could you share your domain with us?
I wonder if it’s related to this (given the error)?
