I am getting the same error during set up. When asked to "sign in" the link appears to be broken with the following error message.
"This site can’t be reached
Check if there is a typo in %22https.
If spelling is correct, try running Windows Network Diagnostics.
DNS_PROBE_FINISHED_NXDOMAIN"
If you correct the error (remove the %22 and add a colon after https:) it still does not continue.
Is there a solution?
