I'm currently restricted to use of my PS3 for internet browsing. I'm aware this isn't the best of options but it's the only one I have.
When attempting to visit a site I received the titled error code and was confused so I googled it. The results of the search proved... unhelpful, being in general related to simple inability to connect to PSN. I have no issues connecting to PSN or browsing the internet in general using my PS3. The only issue is there is one site which defies my ability to browse it, a problem which only started today, and I have no idea why.
