If you are experiencing an issue where you try to log in but are redirected back to the sign-in page, follow these troubleshooting steps to resolve the problem:

1. Clear Browser Cache and Cookies: Sometimes, outdated or corrupted cache files and cookies can interfere with the login process.
- Go to the settings of your web browser.
- Locate the 'Privacy' or 'Security' section.
- Find options to clear browsing data, and ensure you select both 'cookies' and 'cached images and files'.
- After clearing them, try logging in again.

2. Use a Different Browser or Device: Sometimes specific browsers or devices may cause login issues.
- If you're using Chrome, try switching to Firefox, Edge, or another browser.
- Alternatively, try accessing your account from another device, like a tablet or a different computer.

3. Private or Incognito Browsing: Using a private or incognito mode can help to bypass issues related to cache and cookies.
- Open a new incognito or private window in your browser.
- Attempt to log in to your account from there.

4. Disable Browser Extensions: Certain extensions can interfere with standard web functions.
- Disable any browser extensions, especially ad blockers or privacy-focused ones, to see if they are causing the issue.

5. Check Internet Connection: Ensure that you have a stable internet connection.
- Check if other websites load without issues.
- Restart your modem/router if needed.

6. Update Your Browser: Ensure that your web browser is updated to the latest version.
- Go to the settings or help section in your browser and check for updates.

7. Look for Service Outages or Maintenance: Sometimes, the issue might be server-side.
- Check social media or forums for any announcements regarding the service you are trying to access, such as FET.

8. Re-check Login Credentials: Ensure that you are entering the correct email address and password.
- If you have forgotten your password, use the password recovery option.

If you have completed these steps and still cannot log in, consider reaching out to the support team of the service for further assistance.

What causes login loops on web applications?

Login loops on web applications occur when the application continually redirects the user back to the login page instead of granting access. This can happen for several reasons, each of which can be diagnosed and resolved through specific steps. Below are common causes of login loops and suggestions for addressing them:

1. Incorrect Configuration: Sometimes, applications are not correctly configured to handle authentication and user roles. If the application expects certain settings (like an app ID), ensure these configurations are set correctly. For example, upgrading the application might resolve issues related to configuration - learn more.

2. Session or Cookie Issues: If session cookies are not being set properly after authentication, the application may fail to recognize a logged-in user. This can happen due to conflicting domain settings or corrupted cookies. Clearing your browser's cache and cookies can often resolve these problems - learn more.

3. Redirect Loop: If the application is set to redirect users based on certain criteria (like user roles), it could inadvertently send users back to the login page if those criteria are not met. Review the application's redirect settings and ensure that they are functioning correctly - learn more.

4. Network and Driver Issues: Sometimes, external factors, such as network configurations or firewalls, can interfere with the login process, leading to continuous redirects back to the login screen. Check your network settings or disable any firewalls temporarily to rule out such issues - learn more.

5. Single Sign-On (SSO) Problems: In systems using SSO, issues can arise if there is a failure in token validation when an authentication token is rejected or not recognized. Make sure your SSO settings are correct and functioning - learn more.

6. Expired or Invalid Credentials: Ensure that the credentials being used are up to date. An expired password or account lockout can lead to login loops. Resetting your password might help - learn more.

7. Backend Server Issues: Sometimes the problem can originate from the server side if the application fails to communicate with the backend services correctly. In such cases, contacting your IT support for further diagnostics would be prudent - learn more.

By addressing these common issues, you can often resolve login loops and restore access to web applications effectively.
