Same thing with me!!!! i want to learn how to fix that too. im bookmarking this page

Mine works fine i can access it

Moved the thread to the support board since it's a more appropriate place due your question being related to a supposed bug/forum problem.

Not really sure what the exact problem is but those links might help. Just go through the suggested troubleshoot for those error messages. Hard to believe that it's a server-side issue.

Waiting for other solutions. What the fuck i have this problem on my phone too...

Its probably something with your account.
That it does have permission.
I think the forum moderators or Hampa have to deal with this.

Still waiting for a solution.

You've tried logging out of your account then trying to get into the thread?
If that doesn't work, try get a VPN/Proxy(Or just connecting while having your computer connected to a different Router/Modem)

Tried that in past, same shit happens.
