If you're still struggling then the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error typically happens on older operating systems or browsers.

There can be other reasons as well, you can find them listed here -  https://kinsta.com/knowledgebase/err_ssl_version_or_cipher_mismatch/

I actually had this happen recently on one of our tracking servers... I thought it was because it was old and set up before my time... Client Care had no record of our tracking server set up for SSL. 

I am now wondering if Adobe accidentally dumped old servers accidentally (since the CNAME process is quite different now). And because they were so old (the one of ours that broke was done like 10 years ago), they didn't have it properly documented.

Anyway, the solution for us was to contact support and get the server re-setup with a proper SSL CNAME, then I had our DevOPs make the DNS change.

Good Luck

The ERR_SSL_VERSION_OR_CIPHER_MISMATCH error appears due to a lack of “common SSL protocol version or cipher suite support” between a web server and a user’s browser. This issue happens during the TLS handshake process. With that, the browser will automatically display this specific error message. Some common reasons for the error can be such as Outdated browser or Operating system, Web servers employ the outdated RC4 cipher suite, Corrupted SSL state within the browser, Antivirus software interfering with SSL protocols.
