Cannot connect to Webmin though SSL / https://

Hi there,

I’m trying to enable SSL logins for Webmin. I’m following the instructions here: and here:

OpenSSL was already installed by default and so was Net::SSLeay.
If I run perl -e 'use Net::SSLeay' I get no error message.
SSL is enabled.

In Firefox the error message reads An error occurred during a connection to x.x.x.x10000. SSL received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long) . If I look in /var/webmin/miniserv.error I can see “Bad Request” for every login attempt

I’m a bit stuck at the moment.
Am I missing something?

Thank you.
