Load Balancer Monitor

I’ve added a load balancer but cannot get the monitor to work. I tried setting up ICMP Ping as the monitor type but Preview fails every time I run it and it always shows as Degraded.

I’ve verified I can ping the external IPs. I want to use ping as this is an SFTP server and it doesn’t have any other services on it.

Hi,

If you use Load Balancing Analytics or hover over the colored indicator showing degraded, it should show you a reason for the failure and why it is marking as degraded.

If you can let us know what error is being returned there - that should point us in the right direction on what could be causing this behavior.

Typically it would be one of these - Common error codes · Cloudflare Load Balancing docs - but if you are using Ping - then most likely it would be a problem with establishing the connection from our Cloudflare IPs.

regards,
Damian

Failure reason is ICMP timeout occurred for both IPs. I can ping from the command prompt without issue. I also used Online Ping and also received responses.

I have looked at the logging on my firewall and can see where Cloudflare IPs are pinging our system and they are being accepted AND replied to so I’m not sure of the issue.
