Hi,
- To avoid blocking all users, go to the Cloudflare dashboard, select your domain, navigate to the Firewall > Tools, and remove any unwanted IP blocks.
- For the 524 error, try increasing the Cloudflare timeout limit, bypass the timeout limitation by adding your server’s IP address to the local hosts file: https://www.howtogeek.com/howto/27350/beginner-geek-how-to-edit-your-hosts-file/
