remove Mikrotik HttpProxy in v2.9.27

I have Mikrotik routerOS 2.9.27. I have blocked access to the router page 192.168.1.1. and I get the following error message:
Mikrotik HttpProxy
Error: 504 Gateway Timeout

How can I remove Mikrotik word from this?
I was able to do this in v4 but I want to do it for RouterOs v2.9.27

you must upgrade to v4.4
