Icecast - Mar 2020 - SSL connection fails: Invalid or missing password

Hello, 

I have installed and configured Icecast 2.4.4 with SSL in Ubuntu 18.04.3. 

I can successfully connect to the server using the web browser and everything
seems fine.

However, when I try to connect using an Icecast client such as LadioCast I see
the following logs (server side):

[2020-03-31  16:50:29] INFO connection/get_ssl_certificate SSL certificate found
at /etc/icecast2/bundle.pem
[2020-03-31  16:50:29] INFO connection/get_ssl_certificate SSL using ciphers
(key)
[2020-03-31  16:51:07] INFO connection/_handle_source_request Source logging in
at mountpoint "/live" from (ip address)
[2020-03-31  16:51:07] INFO connection/_handle_source_request Source (/live)
attempted to login with invalid or missing password

The credentials are correctly set in the client and obviously not empty.
Actually, if I just remove the <ssl>1</ssl> line from the config
file the connection gets established.

Any ideas?

Please let me know if you need any additional context info. 

Thanks in advance.
