I'm having some problems connecting to an old Radius server that is stuck on TLS1.0

I'm getting error -19 in HTTPClient mode and -33 in RESTClient = "TLS 1.3 error. The server does not support TLS 1.3."

I've set both SecureProtocol and IgnoreServerCertificate to 0 (setting SecureProtocol to 3 TLS1.0, or any other setting = same result -33 or -19)

If I set IgnoreServerCertificate to anything else I get -14 (http) or -25 (rest) = The application experienced an internal error loading the SSL libraries.

 

The application was using an OleObject (Msxml2.XMLHTTP) which started failing (runtime error on obj.send() command), we are thinking the cause is a windows update that started blocking TLS1.0

I changed the code to HTTPClient and RESTClient but keep running into that -33 -19

We know this server will have to be retired and are working to do so but I'm able to get FireFox through so why is PowerBuilder not going through?

(in Firefox I've had to change security.tls.version.max to 3 and min to 1) In Chrome it is not even possible to set those settings.

 

Using the demo site https://demo.appeon.com/PB/webapi_client/employee/102 I get the expected result.

(PB2022 22.0.0.1878 32bit application)
