Content Locker Issue - Need Help

Hi, I content locked an URL in CPAgrip and pasted the content locker link in my landing page's button but people are saying that after putting address, phone number nothing happens when they click "continue". The locker have 5 survey offers and many people have tried 5 options but they saying nothing happens after they press continue. I am not getting leads and they are not getting redirected to the URL.

But yes I got one lead yesterday from the same cpa content locker but today more than 3 people said nothing happens after filling the survey.

Is this a common problem with content lockers or is it with CPA grip only? I'm losing money this way.

Need advice on what to do? Should I change network?
