J-web issue with too many redirects & phone-home

Switch: Ex2300-24P

Version: 18.1R3.3

I'm having issue with web-management interface. If I only have https enabled:

web-management {
            http;
            https {
                system-generated-certificate;
                interface irb.10;
            }
        }

I get err_too_many_redirects error. If I enable http, that works but its not secure.

Also, in one of the switch I'm getting Phone Home Client on the web interface. I saw following in its conf:

system {
    ....
    phone-home {
        server https://redirect.juniper.net;
        rfc-compliant;
    }
}

I can't delete phone-home, it doesn't give me that option:

root@SW-ACC-D01# delete system p
                                    ^
'p' is ambiguous.

root@SW-RCP-ACC-D01# delete system p

I tried deactivate, but same issue. Please bear in mind that I'm remoted in through SSH.

How do I get rid of this and get back to Juniper Web Device Manager ?
