Why do Facebook Login errors occur?

Apart from incorrect account information, software-related factors can also trigger random errors to occur while using Facebook. Ruling them out is therefore a key to obtaining the ultimate solution.

Among the common culprits that you should consider ruling out are minor software glitches, settings conflicts, faulty updates, data corruption and some malware. Network-related problems as well as memory issues on the device are likewise deemed among the underlying causes.

Some Facebook errors are also attributed to ongoing service outages tied to a scheduled server maintenance or unexpected technical difficulties.

Generally, the underlying cause is software-related and therefore possible to fix by end-users.

Outlined below are simple tweaks that are deemed useful when resolving unexpected Facebook problems on an iPhone including login errors. Feel free to try any of the given solutions whichever you think is applicable to you.

Still unable to sign into Facebook and getting the same error message?

If the error continues after doing all the aforementioned solutions, then there must be something else from the iPhone system that’s triggering it. 

At this point, try to verify the date and time settings and ensure that the information is correct. If necessary, set your device to use Automatic date and time information so it will use the same date and time information on your current location’s time zone. Online apps may not be able to work as intended when the date and time is incorrect as it couldn’t synchronize with the main server.

If configuring the date and time information doesn’t do any good, then you may resort to performing the iOS reset options. 

There are different reset options available on an iPhone but you only have to execute the most relevant. In this case, the most applicable resets are the reset network settings and reset all settings commands.

Performing this reset is often deemed among other potential solutions to recurring system errors and in-app glitches tied to settings conflicts from recent system alterations as well as automatic update overrides.

This reset however is different from a factory reset as it does not affect any user information from the internal storage of your iPhone. This means that all your important files will not be deleted.

After the reset though, you will need to re-enable necessary features that are disabled by default and set default apps to process certain file types or data protocols.

C. Uninstall then reinstall Facebook

A drastic solution is to completely uninstall the Facebook app from your iPhone. This is usually needed if corrupted app fragments are the root cause of the problem. The same goes when the Facebook app itself got corrupted as the only way to get it back up and working properly again is a fresh install.

  • To uninstall Facebook app on the iPhone SE 3, press and hold on the Facebook app icon from the Home screen and then release when the quick menu options appear. Tap Remove App from the menu items then tap Delete App from the pop-up warning to confirm.
  • To reinstall the app, just head over to the App Store and search for Facebook. Tap Facebook app from the search results and then tap the Get icon next to it to instigate download and installation procedures.

Unlike offloading, uninstalling deletes everything from the app including your saved Facebook data, images, videos and other added files from your account. In return, you’ll have a fully functional, smoothly working Facebook app on your iOS device.

Could it be a service outage?

If the error continues after applying all the given solutions, there’s a good chance that it’s a meta server issue.
