Error with SSL and any version > 0.27.2 #2185

httpx version: Greater than 0.27.2

Current Behavior: SSL connections rejected by school firewall

If I use any later version of httpx than 0.27.2, our firewall rejects SSL connection requests. I work in a school.

Expected Behavior:

Should be able to use the latest version of httpx but if I do, my SSL calls with the same code get rejected. All good with 0.27.2

Steps To Reproduce:

Anything else:

python version 3.13.1
