ERR_ICANN_NAME_COLLISION .dev account

I'm having trouble accessing my website created on a local server. I get the message:

"This site can't be reached This site on the company, organization or school intranet has the same URL as an external website. Try contacting your system administrator. ERR_ICANN_NAME_COLLISION"

Any advice/step-step solutions? Note: the URL was firstname.dev but I changed it to firstnamelastname.dev while logged into firstname.dev on local WordPress. Than the next day when I tried to go back in to log in via /wp-admin, I got this message. I've tried both URL's. I have a Mac. Also, it's not working on Safari, Chrome or Firefox.

Apparently ".dev" is now an actual TLD and no longer reserved for internal use. Try using ".local" instead.

Still no luck. I tried:

  • Editing host file within terminal by changing IP address, domain name, .dev to .local, #local site etc....
  • Deleting SSL certificate in keychain access
  • Utilizing Local by Flywheel (still a possibility)
  • Rerunning Apache/MySQL

It seems like the solution is different for everyone with this error on forums. I personally decided to start over by re-downloading the desktop server. It showed that I still had two sites. I deleted one, and "moved" another. If anyone finds a better solution, I'd love to hear as I'm still skeptical of this problem reoccurring.
