Hi! I understand you’re trying to log in to your e-Halsangandn account on your Mac with OS X 10.15.7, and even though your credentials are correct, it’s not letting you in. Let’s see what we can do to get this sorted out.

To start, can you tell me if you’re trying to log in through a web browser or through the e-Halsangandn app on your Mac? Also, have you tried any steps already, like restarting the app or the browser, or checking your internet connection?

Meanwhile, here are some initial steps that often help:

1. Double-check the keyboard input: Sometimes, invisible caps lock or keyboard layout differences cause the passwords to be entered incorrectly. Make sure caps lock is off and your language input is set to English.

2. Clear browser cache or app cache:
- If you’re on a browser (Safari, Chrome, etc.), clear the cache and cookies.
- If you’re using the app, try quitting it completely and reopening it. If possible, clear its cache or restart your Mac.

3. Update the app or browser: Since your OS is 10.15.7, make sure your browser or app is updated to the latest version compatible with your system.

4. Try resetting your password from the login page, if that’s available. Some users have reported trouble logging in even with the correct credentials due to authentication issues on the platform. However, if there’s no password reset option, that might be a limitation of the app’s authentication method.

5. Reinstall the app (if using the app): Sometimes the app itself can have corrupted files. Uninstall and reinstall it, then try logging in again.

6. Check for service outages: Occasionally there might be system-wide issues preventing logins. Check for any notifications or status updates on the e-Halsangandn website or support pages.

If none of these help, please let me know if you receive any specific error messages when trying to log in. That info can help dig deeper. Also, if this is the app and you continue having trouble despite correct credentials, it could be an app-side authentication problem which has been reported sometimes.

Looking forward to your reply!
