I have narrowed it down to the IP address, the site works fine on the same computer/browser on any other IP address then when I use my home IP address, the site doesn't or barely works on any browser on my computer and doesn't work on my iphone connected to the IP, turn off the wifi and use my LTE and site works fine, some type of Wierd IP problem? The only site I'm experiencing problems with on my IP is this one, haven't ran into any other problems, I'm clueless on what the issue is, maybe restart the router?
