A. 1. Check internet connection: Ensure you have a stable internet connection. Try switching between Wi-Fi and mobile data to see if that resolves the issue.
2. Clear app data: Go to 'Settings' > 'Apps' > 'ESS 41' > 'Storage' > 'Clear Data'. This will reset the app and may resolve login issues.
B. 3. Use the correct credentials: Double-check that you are entering the correct username and password. If you have multiple accounts, ensure you are using the right one.
