Site Lockout Notification

I recently changed the password to my WordPress admin account and started getting the following emails, sometimes a few in a day-

“User login lockout events had occurred due to too many failed login attempts or invalid username:

Username: helpthinkpla-com
IP address: 162.158.34.139
IP range: 162.158.34.*

Log into your site WordPress administration panel to see the duration of the lockout or to unlock the user.”

I checked with Cloudfare support and they said it’s not a Cloudfare issue and nothing seems wrong in the Cloudfare account. There is no username with that email and everything else seems to be working fine. I am not facing any issues logging into WordPress as well. Since our old developer set it up, I am unable to figure out what the issue is. Any help will be appreciated.

Thanks.
