Log out your account and log back into Facebook
The error occurs due to many reasons, but most are not very serious errors, so we can fix the situation by logging out of your Facebook account and then logging back into your account.
Clearing the Facebook cache is also one of the simple ways anyone can do, this does not affect the data but only deletes temporary files stored on the device to refresh your application.
How to clear the cache:
At the main interface of the phone, click Settings (Settings) -> Manage apps (application management) -> Facebook -> Clear Data (clear data) -> Clear Cache (clear cache) ).
Delete Facebook data
If clearing Facebook cache does not work, we need to continue to delete all Facebook data. Deleting Facebook data will also log out of the account and the images you have downloaded from Facebook, consider synchronizing data before proceeding.
How to delete data:
At the main interface of the phone, click Settings (Settings) -> Manage apps (application management) -> Facebook -> Clear Data (clear data) -> Clear Data (delete data) .
Update application on Google Play
The problem may occur because your device has not updated to the latest version of Facebook, the old version is being used, it will lead to unstable Facebook status. Please quickly go to Google Play to update the application.
If the above methods do not help you to access Facebook stably, please remove the Facebook application from your device and install it again. Removing the application will help you refresh the data and get the latest version.
Download the APK file from an external source
The cause of the error is often unknown, so far, the situation has not improved, try to remove Facebook from the official download link of Google Play and install the older Facebook version via the APK file.
Go to the website: https://www.apkmirror.com/ or APKPure and search for the Facebook application and download the old APK file to install.
Note when installing the APK file:
In Settings (settings) -> Security (security) and activate Unknown sources (of unknown origin) to allow the device to install the APK file.
Turn off battery saving mode on the device

Follow SUSE’s SP7 procedure to enable FIPS mode, reboot safely, verify the active policy, and check whether your compliance requirement calls for validated modules.
Compare YaST and cryptsetup for a new encrypted SLES data volume, choose LUKS1 or LUKS2, and verify unlock and mount behavior safely.
Create, refine, and verify a least-privilege AppArmor profile on SLES 15 SP7, with a clear note on SLES 16’s SELinux default.
Set up RMT on SLES 15, mirror entitled repositories, and verify HTTPS registration and package access from a test client.
Connect SLES 15 to AD with YaST’s SSSD-based logon management, then verify directory lookup, domain login, and Kerberos tickets.
Set up the right Live Patching path for SLES 16.0 or 15 SP7, apply eligible kernel fixes, and confirm what is active without confusing it with a reboot-required kernel update.
Load a custom SLES 15 kernel module without disabling Secure Boot. Match the running kernel, sign the .ko file, enroll a MOK key, and verify loading.
SLES 15 SP5 can migrate online to SP6, but each node must reboot. Use a tested rolling upgrade or blue-green cutover to keep workloads reachable.
Use SUSE’s supported STIG profile to scan SLES 15, test remediation, review remaining findings, and retain assessment evidence.
Trace a failed Cockpit connection through DNS, port 9090, the systemd socket, firewalld, TLS, and login settings using current SUSE guidance.
