SSL/TLS connection

Shanthala Udupa

Hello I am working B.net to configure a remote server , after configuring it's giving following error

The underlying connection was closed could not establish trust relationship for the ssl/TLS secure channel

For this issue I have added following line of code but still giving same error

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 Or SecurityProtocolType.Tls Or SecurityProtocolType.Tls11 Or SecurityProtocolType.Tls12

can you pls guide me what changes I can make for this

Thanks

Shanthala

Sometimes this error happens when the server certificate is not installed in the trusted root certificates.
Maybe you need to ckeck that the certificate is installed, I think the following link can help you :
