Webmin SSL login

Have just noticed that I can't login to webmin. From what I can gather, SSL is not responding and https://mydomain:10000/ times out. Everything else seems to be functioning normally.

Some background if it's of any help:-

1. Upgraded recently to the latest version of webmin 1.410 and as per the insgtructions after the upgrade, deleted /usr/libexec/webmin
2. April 3 gave a cron error:
Error: Invalid module updates source file
Error

Invalid module updates source file

Kindly advise.
