Boto: SSL: CERTIFICATE_VERIFY_FAILED] on s3

[levivm]

I'm trying to upload files to my S3 bucket and I'm getting this error. I tried using boto3 and it worked fine.

    self.name = self.storage.save(name, content, max_length=self.field.max_length)
  File "/usr/local/lib/python3.5/site-packages/django/core/files/storage.py", line 53, in save

Ran into this today as well. Switched to python2 as a workaround.

Found a fix for this, certifi needs to be updated!

Is this still open? The solution by @BossGrand worked for me on python3.6
