[Icecast] Icecast SSL endpoint timeout issue

Hi team,
Please accent my apologies if this is NOT the place/distro list to be
raising this. I had major dramas with the standard forum - registration and
decided this may be a better route.
My current instance icecast server has been built with --with-curl
--with-openssl options as outlined within this post:
https://weekly-geekly.github.io/articles/350236/index.html and the build
version is 2.4.99.2
I'm using a valid certificate from letsencrypt on a Ubuntu 18 server hosted
by AWS. Icecast recognizes this without issue.
I'm having issues disconnecting my source client from Icecast when the
connections is via SSL. Non SSL source clients work as intended, connecting
and disconnecting without issues and Icecast shuts down the mount points
after client drop-outs as intended. See the logs outlined below for details.
Using an SSL connection and once the client connection drops (for whatever
reason) Icecast does not recognize this and keeps the mount point active
forever - even when there's no data being sent by the client. On a
reconnect try the client gets a 'mount point already in use' message. To
get over this state I either have to restart the Icecast service OR manually
kill the source from the admin interface. Once done. I can reconnect
again.repeating the process
Frustratingly, this (SSL) works (source>icecast>listener) - just about -
but I'd dearly like to understand the issue with the ssl connection and
mountpoint not being released. I would expect a source timeout to occur, as
defined in the Icecast config file thus releasing the mount point. However,
not to be.
Connecting to unencrypted Icecast port (8000)
