403 authorization problem

I am only able to access these forums on my mobile phone. My desktop gives me a 403 authorization access problem. My mac and my windows on parallels gives me the same 403 access problem. Can anyone help me fix this?

A web server may return an HTTP 403 Forbidden status in response to a request from a client for a web page or it may indicate that the server can be reached and process the request but refuses to take any further action. HTTP status code 403 responses are the result of the web server being configured to deny access to the requested resource by the client.

A common request that may result in a 403 Forbidden response is a HTTP GET request for a web page performed by a web browser to retrieve the page for display to a user in a browser window. The web server may return a 403 Forbidden status for other types of requests as well.

Do you have an anti-virus or firewall, if you have set the rules on strict it might deny access to the forum.

I do not have anti virus and my firewall settings do not have a strictness setting.

A bit of new information though, when my phone connects to my home wifi, it gets the 403. When I turn off wifi, I can access the page.

Maybe the forum considers your Wi-Fi network as not safe and blocks your access to it. You probably don't have security certificate on the Wi-Fi so it deemed unsafe.

I am finally able to access https://scirra.com on my main computer using my home Wi-Fi, but I can only do this using https://kproxy.com/ proxy server. Does this my my main IP address was somehow banned?
