Redirect traffic to node ip address

I have a public address https://app.abc.com publish on F5 and we have a single node for this.

My application team encounter some error while accessing using the web name and they also enocunter the same issue on the server itself but they have no problem using on the server locally.

I'm creating a irule to redirect to the ip address as below. Will it work as it's production system so I would have only a change window to test it out ?

when HTTP_REQUEST { if { [HTTP::host] equals "app.abc.com"} { HTTP::redirect "" } }
