Can't find a user on Instagram?

[Jazmin]

My friend has an instagram,she's posting her stuff on twitter too,and I clearly see her username,and she said it's right but when I type in search,it says user doesn't exist,when her page exists! Why is that?
UPDATE (lol) : When I log out I can find her,but when I click on her page it says page doesn't exist again. I even tried from my computer,webstagram... :/

It could be for many reasons. Maybe you aren't typing it in right, or maybe you are typing and searching hashtags and not users. When u go to explore and search, there is a bar on top of all results and it says users and hashtags. make sure you are searching users. If you still can't find her, maybe she has privacy settings set so that she is not visible on search. If it still doesn't work then give her your user and ask her to follow you and it will pop up in your news. From there you can follow her. Good luck
