Hi Team,
I've tested the CSharp_Authenticate sample code (https://apiforums.easylink.com/content/c-sample-authenticate-complete-project) earlier and it worked. Now, I'm getting this error. Please advise
"The request failed with HTTP status 407: Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. )."
Sounds like an error on your side. That is not an error we pass back. Did anything change in your network setup? Proxy Server added or removed?
The error pops up while I execute the sample code through VPN connection or within our intranet. It works fine through internet. Is there any specific network ports or services that needs to be opened or enabled, which I can relay to my firewall/network team?
You probably need to grant access to the URL you are submitting to.
I have the same issue. Any examples on how to grant access to the URL?
