Hello,

I have a new problem in ISA server 2004 SP3. When I want to connect to some URLs like (https://www.encrypt.standardbank.co.za/) 502 proxy errors make me surprised!!!!!!!!!! I opened SSL ports 443 and 8443 in ISA server tunneling port and select HTTP 1.1 in internet explorer but the problem is remained. I need some help to solve this problem because my company's money transaction is accomplished by this site and this issue should be solved as soon as possible.

Regards,

Hi,

Enable SSL in your web browser by opening Internet Explorer and then going to Tools -> Internet Options -> Advanced -> Scroll down to security, check ssl 2.0 and ssl 3.0

Hello

yes, it is happening in all clients in the network. I investigated in depth and I found that ISA server request authentication and client is not capable to send any respons to authentication request. for this reason the conection is time out after take seconds.
