It looks like the certs are not quite right in the environment. You don't usually have to reinstall the vApp. Can you please double check the following?

2. Make sure you have added the root and intermediate certs into all VAs (service, connector and data) using the steps described in documentation at this link (Applying SSL Certificate from Private CA)- Horizon Workspace Help
