Hi,

I have set up calendarserver on my Raspberry Pi (Raspbian~Debian) for
personal usage. I wanted to handle all communications on a secure
connection therefore, I do want to use SSL/TLS only. After I set up
everything, I could browse the root directory on non-tls channel. Then I
wanted to create a self-signed certificate to secure the connection. I had
a pair of .pem and .key files, which I referenced in the configuration. I
made sure, they are accessible. Then, I tried to "browse" the root
directory again, but webpage never loaded (it was is being loaded for a
very long time). Then I checked the error.log file and here what I have
found:

I also tried letsencrypt's CA certificate, I had the same problem.
What might be the problem? Is it a bug or the server doesn't like the
certificate for some reason?

Thanks a lot!
