Many Instagram users complain that they cannot log into their Instagram account even though the username and password entered is correct.
When users happen to click log in repeatedly, a notification like Unknown network error, Please try again later or we detected a suspicious login attempt on Instagram might pop up.

These message typically appears when users fail to access their accounts.
A Suspicious Login attempt is Instagram’s way of saying, someone is trying to break into your Instagram account that they do not recognize.
Instagram keeps track of the IP addresses and devices you regularly use.
If they see an attempt to access your account with a device and IP address that Instagram does not immediately recognize, they will sound the alarm and send you a notification.
On the other hand, you could be the one who triggered their security alarm.
If you were logging into Instagram with a new device, then Instagram will see it as a threat.
In that case, it was an honest mistake, but a happy one.
That means Instagram’s security measures are working.
Causes of Suspicious Login Attempts on Instagram
To solve the Instagram login problems, you need to first understand the reasons behind Suspicious Login attempts.
Only then can you detect and solve unusual login attempts or suspicious login attempts.
Here are some reasons why Instagram will notify you with Suspicious Login attempt.
1. Log In attempt with Incorrect Password
Forgetting password is not unusual, with so many login details to keep track of.
We tend to mess up a bit when it comes to remembering password.
If you attempt to login to your Instagram account multiple times with wrong password then Instagram might flag this attempt as suspicious.
You will then be asked by Instagram to confirm whether the account you are trying to access is yours.
Verification can be done by email, cell phone number, Facebook, and other methods.
Verify the confirmation from Instagram if it was you that was trying to genuinely log into your account.
2. Someone trying to hack into your Instagram Account
When anyone makes multiple login attempts and fails to log in to Instagram, they are considered as bad actors.
Usually, you will get a notification informing you about an unusual login attempt on Instagram.
You might receive this message on the Email ID you registered with or on Instagram itself when you log in.
Verify the activity and if you find something unusual then report to Instagram and change your password as soon as possible.
3. Your cell phone is connected to VPN
It is possible that you are using a VPN (Virtual Private Network) on your cell phone or PC.
VPN is generally used to access to the internet from the location of your choice.
For example, if you use a VPN with a IP Address from other countries, Instagram will notice a change in the user location and can flag this log in attempt as a suspicious or unusual login.
Make sure you don't have your VPN on.
4. Instagram Login from a new device
If you are using a new or different device that has never been used to log in can also be flagged as a suspicious login attempt.
Instagram keeps track of which device you normally use, therefore if there is any difference to the device, Instagram will notify you that there has been a login with an unrecognized device.

4. Disable Mobile Data and Switch to WiFi.

When Instagram notices an unknown IP it flags it as unusual and sometimes as a direct threat to your account.
In a situation where you are using your mobile data, and as there is the probability that you are traveling and your network can bounce between different cell towers. When the IP is not recognized or looks unusual from your normal IP address, you will be notified of suspicious activity.
If you ever get such notification then check the activity and make sure it was your login attempt that triggered the suspicious account notification.

Instagram itself has a team that specializes in handling problems experienced by users, do not hesitate to ask questions through the Instagram help feature.
