Resolution: Disable http2 on the IIS and then re-add the product



Instructions:
* Start → regedit
* Navigate to the folder/path: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters
* Under the Parameters folder, right-click the white-space, add 2 new DWORD (32-bit) values:
 – EnableHttp2Tls
 – EnableHttp2Cleartext
* Ensure both new values have been set to 0(disabled) by right-clicking the value and clicking “Modify…”
* Restart the OS.



Misc: To test iis credentials, you can perform the below curl command (run it from a different linux instance as UM has enforced FIPS which disables MD5 for ntlm based authentication)

curl --ntlm --user 'Administrator':'VMware1!' https://iis.ntitta.lab/repository/Data/ManagementModelEntities.svc/ProvisioningGroups -k



Once the above is done, you are likely to run into a second issue, Logs:

GET https://iis.ntitta.lab:443/repository/Data/ManagementModelEntities.svc/ProvisioningGroups failed: Too many follow-up requests: 21=>Too many follow-up requests: 21

To resolve the above, Edit the vRA credentials in usage meter and under the IIS credentials, write the user name in the format: [email protected] and leave the domain field blank

if you see the below:

[2021-03-29 11:29:03]  |  INFO | t_credentials_create | com.vmware.um.vracollector.api.VRAClient | Start test credentials for vRA Cafe server '16'

[2021-03-29 11:29:03]  | ERROR | t_credentials_create | com.vmware.um.vracollector.api.VRAClient | Server '16' failed to authenticate API endpoint identity/api/tokens on server 16 returned HTTP status 400

this means that the vRA credentials are incorrect. Try setting the user name as : administrator and then save.
