I have the same problem. I tried everything. Full repair, Hextech toolkit ,flushing DNS ,starting as admin and even re-install. Nothing works. I was able to ask the support by using my phone because I also only get a blank page when trying to enter the support page through the PC and sent them my LoL Logs like they requested.
So far no response. it seems to be a recent issue though because I was only able to find 2 posts about this so far. This one here and one in german on EUW. Nothing on Reddit either. My guess is that the screwed something up with wednesdays update.
I guess you haven't tried repairing the client because repairing the client is what fixed it for me.
No reinstalling, no flushing DNS or any other methods. Just repair your client again. Otherwise, the problem is not from your bandwidth connection nor your configuration. You will need to wait for the next patch in the worst case.
