Random freeze frames & mega ping spike in Breaches

This has now happened multiple days in a row and it's really getting on my nerves. While doing high level breaches my game (not always) can freeze frame randomly and my ping skyrockets into the stratosphere. After a few minutes, like 2 or 3 max, I get booted to Account Login screen.

This only happens when I try to do Breaches, and it only started happening in high level ones (T15+). I lose any items recently picked up from my inventory. Sometimes it also doesnt count the map as complete, even if I completed the map before starting the Breach. And I've also had it count as a death, because upon loading in sometimes my EXP would've decreased.

As much as I enjoy the Breaches, I am very hesitant to run them regularly like this. Please look into it.
