This is the next part to my post How to Fix the Certs Error in vCenter 8.x in VCF 5.2 where we fixed the certs in the vcenters in both management and workload domains. Now, since the certificates of the vcenters are changed, the SDDC Manager has an issue and when we try to get to the sddc manager URL we get the following error:

The error message says that it has to do with “Identity Internal Server Error” which basically says that it has an issue communicating with the vcenters.

To fix this issue, we will need to download a python script called VcRootCaSync.py from the KB article 316007 and then execute the following command from the SDDC Manager

python VcRootCaSync.py

Once you execute this command from within the SDDC Manager, it will show you the active vcenters and you can pick which vcenter server you want to refresh the root cert in the sddc manager.

In our case, since we have 2 vcenters (management and workload domain), I had to execute this command twice to do the same process for both the vcenters and this fixed our issue with the SDDC Manager UI not showing the Login page.
