Liberty is running inside CICS 5.4 on z/OS

Trying to add a remote liberty server in Eclipse

After I enter the user credentials and server hostname and https port#

I am seeing error on server side:

CWWKO0801E: Unable to initialize SSL connection. Unauthorized access

Client authentication is not enabled on server side

(clientAuthenticationSupported="false")

How do I make it work?

Hi there! You may use the following steps to resolve this issue.

Let's Start with SSL/TLS Certificates.

1. Correct the Date and Time on your Android Device.
2. Clear Browsing Data from Chrome.
3. Change your WiFi Connection.
4. Disable the Antivirus.
5. Restart your Device.

These steps should fix the error you're receiving. If it still fails to work for you. You may ask again. I'll be happy to help you further!

Ecplise is installed on Windows 10. (why Android ?)

No other thoughts on how to add a z/Os Liberty server to Eclipse installed on Windows 10 ?

As I said, the issue is connecting from Eclipse on Windows to Liberty on z/OS.

After looking at the SSL trace I see the following sequence on the client side:

Not sure what "Warning: no suitable certificate found - continuing without client authentication"

in fact means?

The cert <CN=START1, OU=C54WLP, O=IBM> sent by the server is self signed and the CA cert used to sign it was added to the TrustStore on the client side by Keytool.
