Can't connect to BitBucket server with both stashy and Bitbucket modules in Python

[JohnnyAli]

When I try to connect to my company Bitbucket server, I get errors with both Stashy and Bitbucket modules. I gave proper credentials and url and used ssl_verify false, if I don't use it it gets another error, but as far as I know it should work without SSL.

For what I've seen it seems it doesn't log me in I guess.

stashy code :  

import stashy

bitbucket = stashy.connect("company_bitbucket_url", "username", "password", verify=False)
projects = bitbucket.projects.list()
repos = bitbucket.repos.list()

for project in projects:
for repo in bitbucket.projects["%s" % (project["key"])].repos.list():
print(repo["name"])
print(repo["project"]['key'])

Errors are :

File "/usr/lib/python3.6/http/client.py", line 289, in _read_status

Bitbucket module code:

from atlassian import Bitbucket

bitbucket = Bitbucket(
url='***',
username='***',
password='***',
verify_ssl=False)
data = bitbucket.project_list()
dataList = list(data)
print(dataList)
