Changed the name and couldn`t acceed to the website anymore

I created the following URL:
gretate-dg.000webhostapp.com
I was building the website and someday wanted to change the domain name to gretate.dg.
I changed the middle-script for a dot.
Since then, when I want to edit the website with WordPress whith the new name (gretate.dg), this error appears:NET::ERR_CERT_COMMON_NAME_INVALID

And when I put the oldest, gretate-dg, I get into the website without any fomat.

Can you help me? I can’t work anymore with this. Tank you!!
