400 Bad Request: You're speaking plain HTTP to an SSL-enabled server port

Hi All,

I can not find the reason of OHS-WebGate error and I write here, because I assume, it can be an Issue with WebGate-Configuration and OAM:

1- If I click on non-secure URL, e.g. http://mydomain.com:8880/ the Apache redirect URL to secure URL, e.g. e secure URL, e.g. https://mydomain.com:7443/

A- One System works with IE Browser 9.0without issue
B- Another System shows an error message:

400 Bad Request
Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.
