For the machine you got the <WIDE CHAR> error for - did you install 8bit or Unicode?
Your $ZV without the 'U' after the build number, suggests 8bit. I would recommend you install Unicode (8bit support is there more for customers who have legacy 8bit databases).
For the machine you do see the web applications, but can't browse to the page -
Did you enable the Web Applications?
(https://docs.intersystems.com/irisforhealthlatest/csp/docbook/DocBook.UI...)
Are you getting an error when you browse there? (you can check the Browser Debugger just in case)
Might it be an authentication/authorization issue? (you can check the IRIS Audit, making sure you have Login Failure and/or Protect events enabled)
For future reference, it does, as of 2023.2

I think you mean something like this:
