Unable to enable management ui

[weirdyang]

Hi,

I'm trying to enable the management ui plugin, but I get this EACCESS error:

I'm using an adminstrator account, and have disabled anti-virus, and have also opened the default ports. What else am I am missing?

Any help is appreciated, thanks.

RabbitMQ 3.8 has reached end of life in July 2022.

The node tries to resolve its hostname and run into an eacces error from the OS. Perhaps RabbitMQ's account needs some extra permissions.
