Addressing Regular Server Downtime and Website Performance Challenges

Hello,

I’ve been dealing with recurring server outages for the past few days, occurring multiple times each day. These disruptions are significantly impacting the performance and user experience of both of my websites:

1: DDDCodigo
2: * Collegelearnup

I’m unsure whether these issues originate from my hosting provider or Cloudflare. I’m seeking guidance to identify the root cause of these interruptions and to find a solution.

These frequent outages are not only frustrating but also harming the user experience on my platforms. Your assistance in resolving this matter would be greatly appreciated.

Thank you for your support.

Hi there,

Digging around in our logs, this was what I was able to find out.
Over the last 7 days, there have been 60 logged errors on your zone dddcodigo.com.br and of those 30 are 521 status codes.

context: Fail to connect to (origin IP address) cause: Connection refused (os error 111), status: 521

Having said this I would make sure:
1 - The port you’re trying to reach is open at your origin
2 - Cloudflare IP addresses are allowed at your origin without any kind of mitigation.
3 - Cross-reference you origin logs at the time of the errors to search for anomalies.

Error 521: web server is down

Take care.
