Instagram login issue

Successfully created Instagram ac but after closing browser, can't login to instagram. Says, "The username you entered doesn't belong to an account. Please check your username and try again."

What happened to that

Try login with the email.

Search the welcome email from instagram and check the username in that. Use it to login.

get blocked,I guess

Things you can try to log back in
1-Try clearing cookies of web browser, and then again log back in.
2-Try resetting your username or password
3-Change your VPN to another country ( you can get a free VPN from searching free google chrome extension)
4-Maybe your account may have been disabled or banned (meaning you were reported for violating one or more of Instagram’s policy).
5-You can check your account is banned or not by “http://www.instagram.com/[your profile here]” and see if your account pops up. If it doesn’t, then you may have been deleted. Make a new account, or contact the Instagram team.

If this helps you or anyone please give me feedback or maybe a reaction.
I wish you all success in business and life.
Peace

This never happens, probably you would have forgotten your username.

The solution to this:

1. Click on the 'Forgot Password' option.

2. Enter the email id or Mobile number you have created your account with.

3. Click on the 'send login link.'

4. You will get a password reset link, using that you can get back the access to your account.

there is a possibility that they banned your account

Banned?
