PDF font problem (Cannot find TTF TrueType font file "solaimanlipi.ttf" in configured font directories.)

After hosting my websites in cpanel, when I try to generate pdf it shows Cannot find the TTF TrueType font file "solaimanlipi.ttf" in the configured font directories. public function studentPdfCertificate() { $defaultConfig = (new \Mpdf\Config\ConfigVariables())->getDefaults(); $fontDirs = $defaultConfig['fontDir']; $path = public_path("/assets/font/certificate_name"); // font $fontData = [ 'solaimanlipi' => [ 'R' => 'solaimanlipi.ttf', 'useOTL' => 0xFF, ], 'name3' => [ 'R' => 'name3.ttf', ], ];

    $banglaUnicodeRange = '\x{0980}-\x{09FF}';


    if (preg_match("/[$banglaUnicodeRange]/u", auth()->user()->name)) {
        $defaultFont = 'solaimanlipi';
    } else {
        $defaultFont = 'name3';
    }

    $mpdf = new \Mpdf\Mpdf([
        'format' => 'A4',
        'orientation' => 'L',
        'fontDir' => array_merge($fontDirs, [$path]),
        'fontdata' => [
            'solaimanlipi' => [
                'R' => 'solaimanlipi.ttf',
            ],
            'name3' => [
                'R' => 'name3.ttf',
            ],
        ],
        'default_font' => $defaultFont,
    ]);

    $html = view('frontend.pdf.student-pdf-certificate')->render();

    $mpdf->WriteHTML($html);

    $mpdf->Output('student-certificate.pdf', 'I');
}

Here is my pdf controller.
