Windows 10: 404 Forbidden when trying to access forum

Been trying for a long time to log on to a Forum that I had used and it always gives me this
Forbidden

You don't have permission to access / on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
The forum is ApneaBoard.com any help would be appreciated

:)

 

Why my Task Manager don't display the network rate used ?

can you post a screenshot since it showing 404 forbidden when I'm trying to open the website.

 

Error 403-Forbidden when trying to access some sites

Hello Sir, My device is Microsoft Lumia 540 win10. And its OS build :10.0.14393.448. And am trying to open our local official post office website, Orissa Postal Circle-Home Page then this error code show.

 

The forum looks OK to me (as a guest) and I can get as far as the 'register' and 'login' pages too. It may be something corrupted in your browser's cache or its cookies. One quick check for that is to try the site in a private browsing window (so you won't have any existing cached pages or cookies). On all browsers except Chrome you can open one with Ctrl-Shift-P (on Chrome that is for 'Print'). If it works in private browsing then clear your browsers cache and the cookies for the site.

 

What browser are you using? Try clearing the internet cache How do I clear my web browsers cache, cookies, and history?
In addition, contact the sleep apnea's forum administrator and see if they have banned you for some reason: L: apneaboard@gmail.com

 

That's "had used" in the past tense? As in quite some time ago? 2012 by the looks of it. Forum software often includes a option to deactivate accounts after a lengthy period on inactivity. You could try contacting the forum administrator as @spunk suggests.

 

I had no problem getting to the site and some of its pages. It did take me a few clicks to find a page with a Copyright date of 2016. The Forums page shows entries for today. One of the first things I check when sites can't be reached is Control Panel, Internet Options and the Security tab. Sometimes the Default setting is the best.
