We have started with ESP REST API STC with TLS configured. When access it thru web browser with HTTPS, we got error:
Bad Request This combination of host and port requires TLS.
Release : 12.0
Component : CA ESP WORKLOAD AUTOMATION
There are two possible causes:
#1 Sometimes even you enter HTTPS on web browser, it may still be resolved to HTTP.
#2 If you want REST server to actually do the encryption. But if there is also AT-TLS rule for the same port, AT-TLS will encrypt already encrypted communication.
#1 Make sure HTTPS is used.
#2 Check if AT-TLS is set on MVS system; if yes, then the ESP REST API port should be excluded.
