Error connecting to the url

[yustiks]

I am trying to connect to encrypted server. I am running the provided example code from ReadMe:

from requests_pkcs12 import get

r = get('https://127.0.0.1:8443/serviceregistry/echo',
        pkcs12_filename='C:/Users/aa/Documents/project/newcertificates/mycloud.aitia/sysop.p12',
        pkcs12_password='743656375')
print(r)

The output is as following:

This seems to be an issue with requests or urllib3, and not specific to this requests_pkcs2 library. Does any of the solutions offered in in the following Q&A solved your problem?

• StackOverflow: Why requests raise this exception "check_hostname requires server_hostname"?

I tried several of the solutions from stackoverflow, and it did not help unfortunately. =(

Alas, this issue seems to be system dependent, and we can't reproduce it on any of our development systems. Could you run our test suite on your system, please? Perhaps that leads to some insight:

git clone https://github.com/m-click/requests_pkcs12
cd requests_pkcs12
rm -rf .venv
make check

[vog]

@yustiks Have you been able to run our test suite on your system?

no, I was not able to. I developed system without security level

Ok, so I'm closing this issue for now, as we don't have enough information to reproduce it.

Feel free to open a new ticket in case this issue occurs again and you have a system where you can run the tests.
