Issue description
When using a bucket, you see the certificate error: err_cert_common_name_invalid or ssl_error_bad_cert_domain.
Solution
A CNAME record might have been created in the domain management panel, pointing to the <bucket-name>.storage.yandexcloud.net subdomain. Change its content to <bucket-name>.website.yandexcloud.net, where <bucket-name> is the name of your bucket.
For configuring your own domain, see this guide.
