Instagram log-in not working

I can't get the log-in to work. I keep getting this error message: Instagram Login Result: Failed to log in to your account, please check login details. I've tried logging out of instagram on my phone and  browser and retrying the plug-in to no avail. I don't use two step verification. I have a separate log in for facebook and instagram. I'm using the latest version of wordpress with the envato bridge theme. New Macbook pro running catalina. I have requested a refund but if I can get this to work I will remove that request.
