Unable to use SSL

[Rafael Baboni Dominiquini]

Describe the bug
I can't enable SSL in this last version! The previous version was working fine!

To Reproduce
Steps to reproduce the behavior:

1. Edit the config file to enable SSL (ssl_certificate, ssl_private_key, ssl_certificate_chain and ssl_adapter)
2. Execute on terminal "wsgidav.exe -c wsgidav.yaml"
3. See error

Expected behavior
The application should start
