I can retrieve the list of subscribers without issue via the Campaign monitor API wrapper v2 (CampaignMonitorAPIWrapper.dll) when running on my local server.
However, when running the same method (Subscribers.GetActive) on a hosted server (medium trust), I receive the following error:
Source : System
Exception Type : System.Security.Authentication.AuthenticationException
Message : The remote certificate is invalid according to the validation procedure.
Is it expecting the request to come from an SSL environment?
Hopefully this is resolvable, I don't want to have to rewrite all the functionality to upgrade to V3 of the API. If anybody needs the full error report let me know.
Looks to be a hosting related issue, but will post outcome.
