[Membership pro 2] Membership pro 2 = 502

I went to test my stripe payment system live with a coupon. As soon as I took it out of sandbox mode my site crashed and got a 502. If I deactivate MP2 my site is back online. But none of my content is protected.

I am having other issues too, maybe they're related. Here is the other thread:
