thelonelyone23 Do you use a VPN? Or have you tried using one to see if it resolves the issue?
I have the same setup w/ an Index and was having similar issues out of nowhere a few months ago, but in the end after some trial and error figured out it was my ISP throttling the site. Resolved pretty much the second I started using a VPN. I just went with Hotspot Shield since I didn't need anything fancy and the price was right.
