Login Error An Unexpected Error Occurred? Try These 16 Fixes

Login Error An Unexpected Error Occurred

Facebook suffers from errors from time to time. Although they are not often, you may come across them. One of them is a login error.

This is where you try accessing your account and you get a message saying, “login error: an unexpected error occurred”. It is one of the most common errors experienced by Facebook users.

Although the error does not occur quite often or to everyone, when it happens, it surely becomes frustrating since it denies you access to your Facebook account. Very few people have been able to solve this problem. Below, you will learn a list of factors that may cause this problem and how to fix them.

Why Does Facebook Say an Unexpected Error Occurred?

1. Facebook Server Is Down

As much as Facebook is a tech giant and with a very huge number of users across the world, its servers can experience downtime.

It is a situation that has occurred quite a few times and the experience is not good. When this happens, several services or functions from Facebook are not able to work as expected.

The last time their servers were down worldwide, the company made billions of losses. However, users also suffered significantly. This is because the systems are not able to give you the kind of services you are looking and it leaves you stranded.

Note that in some cases, it is not all the servers are down. There are times when only a small section of the servers can have issues. If this happens, you those who are already logged in may be able to access the platform and use it normally, but those who are not will have problems logging in.

Fix – Wait For Facebook To Go Back Up

If you get the login error saying that an unexpected error has occurred, then you first need to confirm whether the issue is the Facebook servers. The first thing to do is go on google and search “Facebook-Server down”. You should be able to get a recent update on the situation and what is going on.

Another way to confirm this type of incident is from your friend. All you need to do is talk to your friend and ask them whether they are experiencing the same type of problem. If they are, then it means that servers are down.

In that case, there is nothing much you can do to solve the problem. You will have to wait until Facebook fixes the servers. It might take a few hours, but you cannot know exactly how long it will take.

2. Facebook Has A Bug

A bug is a technical error within a system or your Facebook app. Bugs happen quite often to technological systems and there is no way of preventing them from happening.

Unlike a situation where the servers are down when the system has a bug, it does not affect the whole operation. A bug can affect just one part of the system and the rest will be working effectively.

So, this means it is possible that a bug has affected the Facebook login system, but those who have logged in are able to use their accounts well. It may also mean that a bug has affected Facebook’s apps, hence those who are using the browser have no problem. On the flip side, it may even affect browsers, but not apps.

The good part is that there is a way you can be able to address the problem of bugs and fix the login error you are experiencing from Facebook. Note that bugs are of different kinds and bring about different challenges. Some bugs are complex that you may not be able to fix.

The process of addressing Facebook bugs causing an unexpected error when you try to log in involves a series of troubleshooting activities. This is done because it is not possible to exactly pinpoint where the bug is. So, follow the steps listed below one at a time until you are able to fix the problem.

Fix – Restart the App

When you are using a Facebook app, and you have been using it for a long time, it is possible for a bug to come in out of nowhere. So, the first step, in this case, is to restart your Facebook app.

2. Now, swipe to the side, and you will find all open apps.

3. The next step is to look for the Facebook app and swipe it up to close it.

4. Go to the Facebook app and open it again.

You can also do this by restarting your phone.

Fix 2 – Switch Accounts and Check

For this second method of fix, you will have to try logging in with another account. There are cases where the bugs might be affecting your account and not others. So, if you have two Facebook accounts, you should try logging in with the second one and see if it will work. If you do not have another one, as a friend logs in using your device.

Fix 3 – Use Facebook.com on Browser on Your Phone Instead

In the course of trying to fix the problem of unexpected error when logging in, you may try to restart the app and switch accounts and still nothing works. At this point, you will have to try and log in to the account using a browser.

Most people are used to the Facebook app on their phones. The error could be in the app without a fix.

So, open a browser on our phone, go to facebook.com and try to log in there instead.

Fix 4 – Use Facebook on a PC

Here is yet another method you should use to address the problem of unexpected errors when trying to log into your Facebook account. Sometimes you may have issues on your phone device that may contribute to this error.

The bugs may be too heavy on your phone that the app and the browser cannot help you.

So, do you have a PC near you? That is what you need to try. All you have to do is open a browser of your choice, open facebook.com, and try logging into your account there. Check whether you are still getting the same problem.

Fix 5 – Switch Phones

Fix 6 – Wait for Them to Come Out with A Fix

The solution is not always to try and fit the problem. This is especially true when you cannot control the outcome. Sometimes the problem could be a small bug in the system that Facebook is aware of.

In some cases, these bugs may disappear on their own within a short time. In other cases, however, you will have to wait for the company to fix them on their own.

Either way, the main challenge is that you cannot tell how long it will take for Facebook to fix this problem. Of course, they will try and address the problem as soon as possible, but you cannot stay on your phone waiting.

Fix 7 – Log Out Then Back In

Facebook allows you to login into several devices at the same time. So, you may experience a login error on one device, but the account is logged in, on another device. The one that is logged in should help you.

Fix 11 – Contact Facebook Support

Fix 2 – Turn Off VPN

VPNs are good but not all the time. Many people like to use VPNs because they know they will allow the browser anonymously. However, there are many instances where VPNs, will interfere with the performance of your device and the apps you have there.

So, if you have a VPN on your phone, start by turning it off. Now go back to your Facebook app and try logging in again and see whether the error is still there or is gone.

Fix 3 – Restart Router

If you are using Wi-Fi as your source of internet, the problem can also arise from the router. When your Wi-Fi router has an issue, the same flows to the devices using the Wi-Fi. Like all other technological devices, Wi-Fi routers also suffer from bugs issue.

As a result, there may be bugs on your router and it is not able to provide the much-needed internet connection hence leading to the login unexpected error on your Facebook account.

Restarting your bug is the simplest method to clear out bugs in its system. It is recommended you do a force restart by unplugging its power cord while it is still on. Wait for between 30 seconds and 1 minute and then plug the power cord back. Wait for it to start and connect your device to the Wi-Fi once more and check.
