What are the common causes of Splunk Forwarder Login Failed?

Are there any risks associated with a failed login attempt?
If you make too many unsuccessful attempts during login process, your account might get locked out temporarily. This means that you won’t be able to access the system until it unlocks after a certain amount of time has passed, so it’s important to ensure that all of your credentials are correct before attempting to log in again.
Is there anything else I should check during my troubleshooting process?
It's important to keep track of any relevant issues related to network connections, updates or changes happening while you're trying to log into Splunk forwarder - these could be causing unexpected errors which need attention as well.
