Redirect to local 192.168.1.1 not working

What type of hardware are you using: Old laptop or computer
What YunoHost version are you running: 12.0.11
What app is this about: Redirect

Describe your issue

I want to access the configuration of the router my host is behind, so I set up redirect to 192.168.1.1
If I set reverse proxy I get 400 “Bad Request”.
If I set explicit redirection it don’t connect at all.
Is any solution or alternative to do what I want?

Thanks in advance.
