SSL Server certificates
Python is strict about certificates when connecting to server with SSL. If certificate cannot be validated, connection will fail. Therefor care must be taken when using self-signed certificates to add their certification authority to trusted certificates.
Also please note that even when using certificates from trusted CA, you need to update your trusted CA certificates bundle as those certificates can change.
So if you receieve SSL error
cannot validate certificate or similar, please update root CA certificate bundle on machines and possibly certifi python package in Pype virtual environment - just edit
pypeapp/requirements.txt and update its version. You can find current versions on PyPI.
