I've had this problem before. What you can try and although this may not be your problem but it seems the url address your link is pointing to may be incorrect. This will happen on some servers where you may have an https and not a regular http. If you see an htaccess file in your folder on the server it's more and likely your url is being rerouted, and you don't have authorization to change it. So here's what you can try to test it if the url is indeed what it says. Your gonna have to make yourself an app with a webview and editTextbox, put the textbox above the webview to you can see the text, have the webview load the link to your app. put this code I listed
EditText1.Text = WebView1.Url
Once the webpage loads you can check to make sure the address is what is says it is. If it's different then there's your problem. You'll need to put the address that appears in the textbox as the link to your app.
