What is the error number?

ERR_SSL_PROTOCOL_ERROR

What is the issue you’re encountering

Based on other posts, I have verified the link is being proxied via Cloudflare, enabled SSL, using Full (Strict) mode, and toggled TLS 1.3 off.

Difficult to reproduce as it only occurs on certain devices/networks

From doing a curl command, I saw the following error:

schannel: next InitializeSecurityContext failed: SEC_E_INVALID_TOKEN (0x80090308) - The token supplied to the function is invalid

Thanks to this post ( Sudden SSL failures - #28 by sandro ), I got the idea of trying a completely new domain (I used a dot com one this time) and it worked!
