On this page we'll walk through some of the most common issues that folks run into when setting a custom domain, and explain how to solve them.
Why I have this error: ERR_SSL_VERSION_OR_CIPHER_MISMATCH?
This error appears because the certificate does not have authorization to be issued.
At certain hosting providers you must add 2 additional CAA records in your DNS:
0 issue "pki.goog"
0 issuewild "pki.goog"
Example from Hostinger.com
Once done, deactivate then reactivate your custom domain in CUSTOM DOMAIN.
If you still have the error 24 hours later deactivate then reactivate again. DNS can take time to propagate.
