Hi @d_sriharsha ,

The err_ssl_version_or_cipher_mismatch error usually occurs when there’s a problem with the SSL certificate or encryption modules. There are a few server-side actions you can take to resolve this issue.

But before that, check the Adobe documentation page below for the TLS versions and ciphers that Adobe Host currently supports:

Thanks!

@d_sriharsha 

Please check the below:-
1) Verify the SSL Status of the Website- Use a free tool like SSL checker.

2) Check for Certificate Name Not Matching.

3) Verify TLS Version.

4) Verify RC4 Cipher Suite.

5) Manually Inspect the Security Certificate by inspecting the browser.

Thanks!

The browser is blocking the Adobe request because it's not secure. 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 reasons can be as follows:- 

1) Outdated browsers or operating systems

2) Old TLS versions are used, significantly older than TLS 1.2.

3) Web servers employ the outdated RC4 cipher suite.

4) Corrupted SSL state within the browser.

5) Antivirus software interfering with SSL protocols.

There are different methods to solve the error. To understand the solution in detail, check here: https://certera.com/kb/how-to-fix-the-err_ssl_version_or_cipher_mismatch-error/. May it be helpful.
