Asked by KNOW Staff
I’ve added a custom domain to App Platform and it works as expected except that the www subdomain won’t load, I get the error:
“This site can’t provide a secure connection www.[my custom domain] uses an unsupported protocol. ERR_SSL_VERSION_OR_CIPHER_MISMATCH”
I’ve tried adding a CNAME record for www as an alias of the custom domain (via the networking tab) and that didn’t resolve it.

Hello there,
DNS changes might take up to 24 hours in order to update due to DNS cache, general propagation time and etc.
You can use our DNS lookup tool and check if the CNAME for the www record is resolving and if not check if you’re actually making the DNS changes via the correct DNS active zone.
