System.Net.ServicePointManager Setting TSL's

System.Net.ServicePointManager Setting TSL's

System.Net.ServicePointManager Setting TSL's

Had a webservice I was consuming throw an error:
An error occurred while making the HTTP request to https://www.odfl.com/wsRate_v4/RateService. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.
The webservice webmaster stated they had upgraded to TSL1.2 over the weekend.

The cure is to set the TSL protocol in my code behind.

System.Net.ServicePointManager.SecurityProtocol = Net.SecurityProtocolType.Tls12

This works. I saw some examples online where it stated I could add a pipe between protocols like this

CODE --> vb.net

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12; 

Problem is it didn't/doesn't like the pipes. "|"

Has anyone had any success adding multiple Protocols.

What is the error or message you are getting?

RE: System.Net.ServicePointManager Setting TSL's

That is C# syntax you are trying to use. You need to put ORs between them

RE: System.Net.ServicePointManager Setting TSL's

HA HA Gee do I feel dumb.

Thank you JB. Appreciate it.

RE: System.Net.ServicePointManager Setting TSL's

nope, don't feel dumb. Just remember that when you google for answers most of them will be C# samples unless you specifically look for VB examples.
I just usually look for the first few find an answer and convert the code if necessary. Here is a good online converter if you ever need to use it:
