Previews deployed to xxxxxxx.yyyyyy.pages.dev give SSL error

same problem as Cloudflare pages - SSL_ERROR_NO_CYPHER_OVERLAP

but all services are green, i’ve waited an hour.

in chrome:

This site can’t provide a secure connection bfb108e7.XXX.pages.dev uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH

in firefox:

Secure Connection Failed

An error occurred during a connection to bfb108e7.XXX.pages.dev. Cannot communicate securely with peer: no common encryption algorithm(s).

Error code: SSL_ERROR_NO_CYPHER_OVERLAP

my system:

System:
  Host: brass Kernel: 6.6.13-100.fc38.x86_64 arch: x86_64 bits: 64
    Desktop: GNOME v: 44.8 Distro: Fedora release 38 (Thirty Eight)

chrome:

firefox:

Solved it by blowing away the entire project (and yes… disassociating my custom domain too) and recreating it.

hope this doesn’t happen again… not very inspiring.
