Resolution

Do some checks to your system first:

1. Check if z/OSMF is up running. The default job name of z/OSMF is IZUSVR1 and IZUANG1.
   1. Take a look at the JES2 job list.
2. Check if z/OSMF is accessible at the specified URL .You can use  your web browser.
   1. Visit the protocol://www.example.com/zosmf in your browser (the computer must have access to the LPAR). If it is accessible, you should see a big "Welcome to z/OS" logo.
3. Call z/OSMF using cURL by the following command:
   1. curl -k -H "X-CSRF-ZOSMF-HEADER: true" protocol://www.example.com:PORT/zosmf/info

Be sure to do it in the USS of the LPAR where Zowe is running.

If z/OSMF is accessible, you should see something similar to the following:

{"zos_version":"05.29.00","zosmf_port":"port number","zosmf_version":"29","zosmf_hostname":"your domain","plugins":...

If you cannot see this but you are sure z/OSMF is running, you will need to ask your system administrator for help. Maybe a firewall or a network policy facility (e.g., pagent) is blocking traffic to the PORT.
