relationship with remote server". Ive tried searching for this on Google many times and have not found a suitable fix. We have also tried to copy (and install) the ROOT and intermediate certificate in the chain to the device, but this still does not work. When we test the new certificate with a PC web browser (IE, Firefox, Opera), a Desktop application that consumes the web service (.NET 3.5), and even Internet Explorer on the Windows Mobile device the .NET web service definitions/documentation page is show without problems (no warnings, or errors), it seems to only be an issue on the windows mobile device when using a compact framework (3.5) application is trying to consume the web service. We have validated that the certificate is installed correctly on the SSL shopper site, and after our google searches we came across and implemented (as a test) a "trust all" ICertificatePolicy handler, this has resolved the problem, however i was hoping that this problem could be addressed by configuration/setup change rather than a code change and a re-deployment of over 150 windows mobile based devices. The ICertificatePolicy hander did show up the error that was being returned when trying to validate the certificate: the problem parameter was set to: -2146762481 (0x800B010F in HEX), which i believ

problem It is frequent that you will need to system.net.webexception the underlying connection was closed the connection was closed unexpectedly either consume web references or expose web services that are called in secure HTTP (HTTPS). In could not establish trust relationship with remote server compact framework that situation, you may run into problems if the certificate you are using in your web server, or the certificate in the server exposing the service http://stackoverflow.com/questions/9364690/could-not-establish-trust-relationship-with-remote-server-error-when-windows-m you are consuming, are not issued by a trustworthy authority. In such cases, you may be presented with an error similar to the one below: Server was unable to process request. ---> The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. This scenario becomes more https://www.outsystems.com/forums/discussion/5690/web-services-could-not-establish-trust-relationship-for-the-ssl-tls/ frequent in the non-productive environments - it is frequent that companies purchase certificates for the production servers, but install self-issued certificates for the other staging environments. Resolution To overcome this error, you need to install the certificate that is used by the web service provider in the server that will be calling the web service. If you are consuming a service provided by a third-party vendor in your OutSystems Application, then you need to install the certificate from the third-party vendor in the OutSystems server; If you are exposing a service for a third-party entity, then they need to install your certificate in their server. Obtaining the certificate To obtain the certificate, you can either: Ask the vendor for it (you can ask them for the Root CA certificate, so you can at once authorize all the servers from them you might need); Obtain it yourself: using Internet Explorer or other
"The underlying connection was closed: Could not establish trust relationship with remote server." This indicates that the client is unable to negotiate a secure connection with the server. Try visiting the URL of your web service http://weblogs.asp.net/tgraham/213469 with IE. You will likely get a Security Alert message box warning about one https://www.experts-exchange.com/questions/28423278/The-underlying-connection-was-closed-Could-not-establish-trust-relationship-with-remote-server.html or more of the following: 1) The certificate is not from a trusted authority. This happens if the issuing authority is not trusted by the Certificate Manager. For testing, you can issue your own certificates and add yourself to the trusted authorities list. For production, you should probably buy a certificate. 2) The date on the certificate is invalid. could not The certificate's dates don't match those on the client computer. If this happens only on some computers, check that the clock on the offending computers is set to the right day. 3) The name on the certificate does not match the name of the site. Most certificates are issued with a www prefix; for example: www.yahoo.com. If your web service is hosted on a named server, (daffy.yahoo.com) you will get this warning. I understand could not establish you can buy wildcard certificates that accept any server name, but I've never used them.
Once you know the problem, you can decide to fix it, or ignore it when establishing the connection. The following class shows how to selectively ignore any CertificateProblems that you choose. Use this carefully, as establishing a secure connection to an attacker's server is worse than sending data in the clear. using System;using System.Net;using System.Security.Cryptography.X509Certificates;namespace Graham.Utilities{ public class AcceptServerNameMismatch : ICertificatePolicy { // HACK: This is a workaround.

The website sends a request to an external website and receives a response that it has to process. All this was working fine until we renewed the SSL certificate on the server. Now after we send the request to the external website, it does not send a response but throws the error The underlying connection was closed: Could not establish trust relationship with remote server.at System.Net.HttpWebRequest.CheckFinalStatus() at System.Net.HttpWebRequest.EndGetRequestStream(IAsyncResult asyncResult) at System.Net.HttpWebRequest.GetRequestStream() I made changes in the code by implementing System.Net.ICertificatePolicy but it still does not work.
