How to solve the error of this site in the photo I installed the certificate but it did not help
The pictures never loaded
Those are not Let's Encrypt certificates.
Also, there are no public certificates issued for the hostname shown in the address bar: crt.sh | dentalestrela.shopping.marketup.com
And there are also no Let's Encrypt certificates issued under the (sub)domain shopping.marketup.com: crt.sh | shopping.marketup.com
That is a certificate from GoGetSSL
This is a forum to help with certs from Let's Encrypt
You should contact the place you got those certificates from or the hosting service you use for that site.
