403 Access to localhost was denied, gulp-connect-php, browsersync - php

Question

Receiving a 403 Error using gulp-php-connect with browser-sync. Identical configuration to another computer which does not produce the error.
Gulp CLI v2.3.0
Gulp Local v3.9.1
Node v10.16.3
Have attempted to change ports. Receiving error on localhost:2000 as well as proxy. Any point in the right direction would be much appreciated.
my gulpfile:
// Gulp 3.8 code... differs in 4.0

php2html = require('gulp-php2html'),
gutil = require('gulp-util'),
browserSync = require('browser-sync').create();

php.server({
