It’s not you; lots of DDoS attacks are occurring on tier 3 ISPs, which is affecting a lot of players’ connections to the servers. Somewhere on the route between your system and SE’s servers, there’s a lot of bottlenecking, congestion, and interference, which can make for high latency and dicey connections once your system finally connects to the data center. Most any of us can really do is wait for the attacks to stop while SE tries to work with their ISPs to resolve and mitigate the problems.
