Installation Failed for vRA 7.4 in the Web configuration stage, I revert IaaS server snapshot but when I tried to retry the installation again the faced the following error related to Certificates:
Message: Command execution failed. Error: An item with the same key has already been added.
System.ArgumentException: An item with the same key has already been added.
at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
"executionOutput": "Installing certificate...\r\nCertificate installed successfully.\r\nExecution time:00:00.032\r\n"
What type of architecture are you attempting to deploy here? If you can, go back through the installation wizard and take screenshots of every page that shows the values you're providing. I know this sounds tedious, but it's the best way to get an understanding of your environment without going back and forth for dozens of posts.
I am using Enterprise Deployment, 3 Nodes for vRA Appliances, 2 Nodes for IaaS (Web, Manger), 2 Nodes for Agent and 2 Nodes for DEM Worker,
After retrying many times it installed pass some steps till creating the DB and no failed in WEB configuration
I will post the screenshots shortly
