SSLError(SSLError(1, '[SSL:WRONG_VERTION_NUMBER]

[c-rei]

When I remake my box applications with python 3.8, I got an error like below.
And my box applicaions worked finely with python 3.5, so I want to known what's wrong with my approach?

Thanks any helps.

My environments:
Windows 10 pro
python 3.8.8
boxsdk 2.11.0
