Hi! I understand you’re having trouble logging into the Holman Insights app and on the web browser from your laptop. Let’s start by narrowing down the issue.

Could you tell me:

- Are you seeing any error messages when you try to log in? If yes, what do they say?
- Have you tried logging in with the same credentials on both app and browser?
- Did you recently change your password or have any account updates?
- Are you connected to the internet and able to access other websites?

Meanwhile, here are some simple steps we can try:

1. Double-check your username and password for any typos.
2. If you recently got a new password, make sure you’re using the updated one. Sometimes new users need to change their temporary password first on the web portal at https://insights.holmanfleet.de/ before using app login.
3. Clear your browser cache or try a different browser on your laptop to rule out browser issues.
4. On the app side, restart the app or reinstall it if possible.
5. Verify that your internet connection is stable.

Let me know what you find from these, and if you get any specific error messages. That way, I can guide you through more targeted steps. If needed, we can also check your account status or escalate to Holman support for deeper help.

Your login attempt was not successful. Please try again.

Thanks for sharing the error message "Your login attempt was not successful. Please try again." This usually points to an issue with the credentials or the initial password setup.

Since you mentioned trouble logging into both the app and web browser, here's what we can do step-by-step:

1. If this is your first time logging in or you recently got a temporary password, you will need to change your password on the web portal before logging into the app. Please visit https://insights.holmanfleet.de/ and follow the prompt to reset or change your password. This is a required step to activate your account8.

2. Make sure you use the exact username/email and the newly created password when logging in on both the app and browser.

3. Double-check for any accidental spaces before or after your username or password when you type.

4. If you already reset your password correctly and still see this error, try clearing your browser cache or use a different browser on your Windows laptop.

5. Restart your Holman Insights app or, if needed, uninstall and reinstall it to clear any app-specific issues.

Let’s start here. If the problem persists after confirming these steps, I can guide you through checking account status or assist with a support escalation.

Are you able to access https://insights.holmanfleet.de/ and attempt the password reset or initial password change?
