Hi, we had a company create our website and they were using certificates from lets encrypt authority x3 however the certificate expired 4 days ago and we contacted them to fix it and they originally said yes however now the company has dissapeared all company contact numbers and business numbers have been shut off and emails are bouncing back.
Is there someway we can activate our certificate without them? we have no access into the backend of our site
My domain is: www.allstarcheerleaders.co.nz
I ran this command: www.allstarcheerleaders.co.nz in URL
It produced this output: certificate expired 13th March 2019
My web server is (include version): Google Chrome Version 72.0.3626.121
The operating system my web server runs on is (include version): Mac OS
