There could be several reasons why you are unable to login to your Facebook account despite having a stable internet connection. Here are a few possible solutions you can try:

1. Clear your browser's cache and cookies: Sometimes, stored data in your browser can cause issues with logging in to websites. Clearing your browser's cache and cookies can help resolve this issue.

2. Try using a different browser: If you are experiencing issues with logging in using Chrome or Opera, try using a different browser such as Firefox or Safari to see if the problem persists.

3. Check for any browser extensions or plugins that may be causing the issue: Disable any browser extensions or plugins that may be interfering with your ability to login to Facebook.

4. Reset your password: If you are still unable to login, try resetting your Facebook password to see if that resolves the issue.

5. Contact Facebook support: If none of the above solutions work, you may need to contact Facebook support for further assistance with logging in to your account.

It's also possible that there may be a temporary issue with Facebook's servers that is causing the problem. In this case, you may need to wait for the issue to be resolved on Facebook's end.

Possible Causes:

- Temporary Facebook outage: Facebook experiences occasional outages that can affect login functionality.
- Browser cache or cookies: Accumulated cache and cookies can interfere with login processes.
- Firewall or antivirus software: Certain security settings can block access to Facebook.
- Incorrect login credentials: Double-check that you are using the correct email address and password.
- Device compatibility: Make sure your device and browser are compatible with Facebook's login requirements.
- Phishing attempt: Beware of fake login pages that may appear identical to Facebook's but are designed to steal your credentials.
- Account suspension or restriction: If your account has been suspended or restricted, you will not be able to log in.

Solutions:

- Check Facebook's status: Visit Facebook's help page (https://www.facebook.com/help/261428586469196) to check for any reported outages.
