Hi,
Yes sometimes Instagram accounts may face this issue. Actually you are login from your web server through the plugin and your Web Server location maybe different from your routine Instagram login location. That’s why Instagram may show ‘Challenge require’ message to some users.
Well this is Instagram security and it all depends on your login history. If you keep login from a specific location for most of the time and suddenly?change your location with a new device, Instagram may trigger it as wrong login and may show this warning. Its same like you change your mobile device.
To resolve this, you need to login to your Instagram account via the official website or your mobile device. You will see ‘unusual login attempt’ warning there.
The area which is showing unusual login attempt is your Web Server location.
You need to keep pressing ‘This was me’ until Instagram accepts your new login location. Nowadays its taking more time to proof new location due to tight security from Instagram. But sooner or later, Instagram will accept it. You may try with a break. Like a day or two and keep repeating it. But don’t try continuously. In some cases, keeping logout from your account from all devices for few days and then try to login through plugin will also be an effective way to connect.
Or you can try by logout from every device, then use any vpn like browsec or hotspot shield and set location of your web server (The area which is showing unusual login attempt is your Web Server location.) Now login from official website of Instagram, logout and wait few hours. Then try login from plugin. That may work.
But please note that these all are tricks and still its up to Instagram security if it satisfy or not.
Another option is to use PROXY for your region to avoid any location change. Proxy option is available at plugin’s login page.
Just for information, if you create a new Instagram account, it will have no location issue and you will connect immediately.
Hope that will help.
Regards
