how to solve bad request 400?

hello!

i add 5 account to mass planner, 4 of them stuck on email loop verify.
i try few times then stop to not banned them.

now i try from my tablet, i use the proxy, clean eveyrthig, and i am getting bad request 400, what should i do?

same problem with fucking email verification loop *-*

Haaalllppp.
Well, seriously anyone resolved this? I tried with blue stacks and failed, firefox with proxy also failed. Tried the MP email verification loop solver something, failed but will try it out again with different proxies later.
