[issue45487] SSLEOFError regression with certain servers in Python 3.10

Never mind, I found the root cause after some debugging. Adding AES256-GCM-SHA384 to the cipher string resolved the issue.

And now I see that the release notes say this:

> The ssl module now has more secure default settings. Ciphers without forward secrecy or SHA-1 MAC are disabled by default. Security level 2 prohibits weak RSA, DH, and ECC keys with less than 112 bits of security. SSLContext defaults to minimum protocol version TLS 1.2. Settings are based on Hynek Schlawack’s research.
