If I access the UI via "ALIAS"
I get the Error-Page "The client is not authorized to request an authorization.
It's required to access the system using FQDN.
What can I do to get UI working through
ALIAS and real hostname?
The Hosted-Engine should be installed &
configured with the correct FQDN to begin with. Changing it post install
is currently unsupported & can cause a whole host of problems.
There are a couple of documented cases where people have attempted to do
so with varying success, but non have come out problem free.
I'm
currently in the same situation after a company domain change and have
decided that the risk of unforeseen issues & potential problems down
the line, are far greater than the pain of redeploying & migrating
to a new environment.
A really hacky hack,
without interfering with the engine, would be to try & put a reverse
proxy in front, but that'll require a load of dynamic rewriting filters
to work.
