Good day,
I have 6 pieces of VPS. All is the same (4 core, 8GB ram, 200GB ssd...) from the Contabo.
On 5 have aaPanel and on 1 Plesk.
When create a new subdomains like seo.mysite.com and with CloudFlare target to the VPS, then 3 of them get back Error 522: Timeout. Why? In all 5 fail2ban have set CloudFlare and the test connection is working. Same settings (OLS, PHP 7.4, MariaDB 10.5).
Where search the problem?
