After os update all my domains were running perfectly.

But today when i access all my domains.

Prior to this i only used one command i.e.

Code: [Select]

sh /scripts/update_cwp

Are you using CloudFlare? It had an issue a few minutes ago.
All my sites showed 502 for 6-7 minutes due to that.

Its due to cloudflare

Yes i am using CloudFlare. But Cloudflare says its because of the status sent by origin server.

Yes confirmed by cloudflare..
Received a mail for the same:

Today at approximately 13:42 UTC we experienced a global service disruption that affected most Cloudflare traffic for 27 minutes.

The issue was triggered by a bug in a software deploy of the Cloudflare Web Application Firewall (WAF) which resulted in a CPU usage spike globally, and 502 errors for our customers. To restore global traffic we temporarily disabled certain WAF capabilities, removed the underlying software bug, then verified and re-enabled all WAF services.
