Hello, the problem integrate vrealize Business v7.6 with vrealize Automation v8.

Hi,

You may try the below:

1. Change hostname so that it matched the DNS name, vRB deploys with localhost.localdom as it's hostname

2. Reissue SSL certificate with common name matching DNS name

3. Unregister and register vRB with vRA and reboot and check the issue.

Assuming that's not a typo, vRA 8 has no integrations with vRB which is an EOL product.

vRAC/vRA 8 will have some measure of integration with Cloud health/vROps for costings.
