ssl.SSLEOFError: EOF occurred in violation of protocol (_ssl.c:2427)

[pgtruong]

Trying to upload a large file to a shared google drive (about 4.5 gb). This used to be intermittent before but is now consistently occurring. I am running on a docker image (python:3.11) and am unsure why this is occurring. I've tried retrying the calls and made sure the packages were all up-to-date. Currently using ServiceAuth as well. This has been working for awhile but has just now been erroring out.

Tbh, can be a lot of reasons, most likely not related to PyDrive itself, but rather some specific misconfiguration / incompatibility in SSL stack (which is pain).

• Could you do some checks here https://stackoverflow.com/questions/33410577/python-requests-exceptions-sslerror-eof-occurred-in-violation-of-protocol ?
• Do you run it in some enterprise / corporate environment where you have proxy, customer certificates, etc, etc?
• Can you try to reproduce it on some other machine / different environment?
• Could you share a script that I could take an try to run?

I've tried to reproduce on my end:

DVC is using PyDrive internally.

What else am I missing here?

Closing for now.
