Getting ERR_NAME_NOT_RESOLVED when trying to clone my main site

I’m trying to clone my main site to a new one using Cloner, but right after clicking on the ‘Clone Site’ button I get this error: DNS_PROBE_FINISHED_NXDOMAIN and then I get ERR_NAME_NOT_RESOLVED.

I’ve tried a couple of times using the ‘Create a New Site’ option and selecting all the tables and the new site is appearing under the sites listed under /wp-admin/network/sites.php, but when I try to access it I get ERR_NAME_NOT_RESOLVED.
