Have you tried flushing your DNS or forcing the computer to use a public DNS server? If so, does this have any effect on your access, or does it still say it’s taking too long to respond?
Unfortunately, this isn’t something I’m able to offer. However, there are a few IT support companies on QuickFile who may be able to help with this. However, we have posted instructions on changing your DNS servers in this thread which you may wish to try. This has been successful for several users. Although, it should resolve itself shortly but does depend on your internet provider unfortunately.
