Showing error that "Application error. Incorrect user name or password or account is temporarily blocked"

After signing into the Grafana Application the message shows “Application error. Incorrect user name or password or account is temporarily blocked”.
Also we have integartion of Zabbix and Grafana. It seems that grafana is not fetching data from database.
Also I’m looking for freelancer for Grafana support
