Can't log-into Virtualmin/Webmin SSL/Connection issue?

I have an issue trying to access Virtualmin/Webmin on one of our servers the browser complains about the connection says…

Secure Connection Failed

An error occurred during a connection to SSL received a record that exceeded the maximum permissible length. Error code: SSL_ERROR_RX_RECORD_TOO_LONG

Please, can anyone advise how I can fix this issue to be able to get access to Virtualmin/Webmin?
