As mentioned in last comment both versions are quite old and no longer supported.

You can try below and see if it helps, this will actually force the vcenter certificate to be trusted across all connection servers:

• Export  and save the vcenter certificate from the browser.
• Import above certificate in 'Trusted root cert authorities' on ALL connection servers and on composer server as well.
• Restart connection server services.
• Restart view composer services
• Check now if it shows green or allows you to manually verify.
