Unexpected disconnections

Hi, all day I’ve been getting unexpected disconnections shortly after logging in usually within 5–15 seconds. I have no idea what’s causing it. I’ve never had this issue before, and I was able to play this league earlier without any problems.

I forgot to mention that I did files verify, cache clear, etc

Can confirm there's something going on. Been trying to join my friend's hideout and if it does let me in, my ping is anywhere from 180 to about 20,000..and most of the time I get dc'd. He's in EU and I'm in NA. He's fine coming to my hideout and I'm fine in my own.
