Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
if you use wix, there should be an integrated solution. If the certificate is expired (your www-version runs on wix and has an expired certificate), you should ask wix why the renew doesn't work.
The security certificate we are having trouble with is from Let’s Encrypt. Both WIX and the domain host said that their certificates are renewed and up to date. Attached is the screenshot for your reference, thanks
