Problem with ligature transformations in embedded font

Question

I am new to using ligatures in an embedded web font. I have built a custom font with a specific ligature that will embed a logo (glyph) when a series of chars are typed. It works perfect everywhere but when its embedded on my site. I have tried all kinds of permutations of font-variant-ligatures but to no avail the transformations will not appear. I have tried WOFF, WOFF2, OTF, and SVG formats what am i doing wrong?

    @font-face {
        font-family: '4ORE';
        src: url('.../files/4ORE-Regular.woff2?v=1607563116') format('woff2'), /* Modern Browsers */
        url('.../files/4ORE-Regular.otf?v=1607563219') format('opentype'); /* Safari, Android, iOS */
        font-style: normal;
        font-weight: normal;
        text-rendering: optimizeLegibility;
    }

    body, html {
        padding: 0;
        margin: 0;
        font-family: '4ORE' !important;
        font-variant-ligatures: normal;
        font-feature-settings: "liga", "clig";
    }

and the font feature code is as follows:

    feature liga {
        # GSUB feature: Standard Ligatures
        # Lookups: 2

        script latn; # Latin

        lookup liga_latn_2 {
        # GSUB lookup 9, type 14 (Ligature)
           sub f f i by f_f_i;
           sub f i by fi;
        } liga_latn_2;

        lookup liga_latn {
        # GSUB lookup 10, type 14 (Ligature)
            sub f f l by f_f_l;
            sub f l by fl;
        } liga_latn;

        lookup liga_latn_4 {
        # GSUB lookup 11, type 14 (Ligature)
            sub four o r e by four_o_r_e;
        } liga_latn_4;

        language FRA ; # French
        lookup liga_latn_2;
        lookup liga_latn;

        language AZE  exclude_dflt; # Azerbaijani
        lookup liga_latn;

        language TRK  exclude_dflt; # Turkish
        lookup liga_latn;

        language MOL ; # Moldavian
        lookup liga_latn_2;
        lookup liga_latn;

        language ROM ; # Romanian
        lookup liga_latn_2;
        lookup liga_latn;

        language CRT  exclude_dflt; # Crimean Tatar
        lookup liga_latn;

        language NAV ; # Navajo
        lookup liga_latn_2;
        lookup liga_latn;
    } liga;
