Is there anyway to ignore this error, and continue? It seems the remote certificate is not signed.

Returning true will allow ignoring the validation error: ServicePointManager .ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true; share|improve this answer answered Apr 20 '10 at 12:48 Peter Lillevold 26.1k570113 5 This is even more useful than it may at first appear. I ran into the OP's problem while using Managed Exchanged Web Services (EWS). I thought that I could not use this answer since I didn't have access to the low-level SOAP calls that were being made by that managed library. But when I took another look at it, I realized ServicePointManager stands on its own. So,I added the above callback before initializing the ExchangeService and it worked like a charm. –Mark Meuer Apr 19 '12 at 21:50 1 This works perfectly for me... But have no idea why... –Pogrindis Jul 10 '15

I have developed a web service which until now has been running locally using http, however it has been moved externally and needs to communicate via https. The certificate for testing purposes is self-signed and therefore not trusted and I am getting the error The provided URI scheme 'https' is invalid; expected 'http'. Web.config

This happens with some frequency when integratingin non-productive environments, since the certificates installed on those environments are usuallyself-signed. Resolution Navigate to the service URL using a browser, and check for certificate errors.

Make sure the URL you're using and the URLon the 'Issued to' field of the certificate are the same; The certificate expired. Install a valid certificate, or contact the support of the system you're trying to integrate with; The Certificate Root Authority that issued the certificateis not trusted by the server.
