[Client] Unknown errors

So this has been happening on a semi-regular basis for the past week or so. I'll try to leave a queue or log out or whatever and it says it's retrieving data from the server for like, a minute straight even though your internet is just fine (long enough for the cancel button to appear), and then when it finally gives up (with you still in the queue/logged in) there's a pop-up saying an unknown error occurred. Often times I have to close that pop-up three times because I guess three errors occurred?

It's a lot rarer when logging out, but it seems to happen somewhat consistently if I check my summoner profile while in queue (for that matter the summoner profile seems to be taking unusually long to load. The background and whatnot will change but the portraits for top champions and the emblem for your division take quite a while to show up)
