Last week we had problems using CloudFlare services.
Site dev.h24.ua
We get errors 403 502 and others.
Here is an example of an error while receiving the file:
When we receive the file /assets/img/preview.jpeg from the server, we get a 403 error.
But directly downloading this file is a file without any problems.
When we set the DNS record mode to DNS only, access to the site is successful.
