This is the Player Forum. No one here can see your game & we don't know which gate your referring to, nor what you've done to try to open it. Without further details, or a screenshot of what you need, we can't be of assistance.
If you'd rather have SUPPORT look at your game (no reset, but they'll help by doing the task for you or give you instructions via email) then you'll need to create a help ticket via this link:
Choose a category on the lower 1/2 of the page. Don't type in the white search 🔍 bar, as it will lead you back to the forum.
