WPT run rejected on Private instance but runs on Public one


Please can you provide some insight as to why on a public instance I can get a web page to be tested but for the same URL on a private instance, the site always rejects the request? ( eg a Navigation error 403)

This is not a common issue, so I know the private instance is working fine, but appears to be consistent on some URLs.

Hard to say for sure but it would likely have to be something about the IP addresses that testing is being run from in the private instance. The URLs in question may have whitelisted the public WPT IP addresses or blacklisted your private instance IP addresses. The actual agent code should be identical.

Thanks Pat, I will investigate further on that basis
