Hello all
I have an environment, VCF 4.5 running on VxRail. Experiencing a multitude of issues related to inventory service authentication, SDDC Manager not able to sync with vCenter and NSX Manager with the password.
Issue 1.
When trying to initiate calls via API Explorer I am getting a bad gateway error per the entries from the log show below:

I found the KB article shown below but that did not resolve the issue.
SDDC manager UI is loading with 502 Bad default gateway error
Further digging into additional logs I found the following errors

I am bit stuck, so I thought someone may have seen this issue and provide any tips on how I can resolve this issue.
Thanks in advance...
