8.6 - Restore Portal on different server - Installation failed. Certificate verification failed: certificate invalid.

[aeph]

Hello everyone,

we have a multi server setup with Management Server, Proxies and a dedicated server for the restore portal. Upgrading the management server and proxies from 8.4 to 8.6 worked out but when trying to install the 8.6 version on the Restore Portal server, installation failes with: Installation failed. Certificate verification failed: certificate invalid.

Restore portal was working well before upgrading.

Already created a support ticket: Case #08250487

If someone was able to solve the issue, let me know. Working on this case with support.
