Hi @Battant, this appears to be a connection issue with the server you have set up, likely with the TLS configuration.

This doesn’t appear to be a defect specifically with Requests from the information provided. I’d recommend testing some other tools like curl and/or postman and seeing if it’s reproducible there. If not, you can open a question on stackoverflow with the python-requests tag and look at debugging options there. Thanks!
