502 Proxy Error - 20.Aug.2007 11:12:02 PM

Users are getting the following errors in their browser when they access a SSL linux web based appplication,

Error Code: 502 Proxy Error. The specified Secure Sockets Layer (SSL) port is not allowed. ISA Server is not configured to allow SSL requests from this port. Most Web browsers use port 443 for SSL requests. (12204)


They can access it without using proxy. They're are using ISA2006, with one network card. It should be SSL custom port to access that appplication, due to user need to type https://10.177.1.2:8443 to access it.

Anyone experienced this before? What kind of configuration need to be done on ISA2006?

Thanks.

 Thanks Tarek, users are able to access it already.

But the ISA is facing another problem right now. In event log, it shown 'ISA server was unable to write content to cache file. event_ID:14197'

Their server got 2 partitions, system C: (40gig) and data D:. I created the cache in D:. And it shown the cache unavailable right now, even if i diable and enable it.

Do you have any idea that anything go wrong?
