Retried single replica

Question

Hi,

I’ve never seen this error before. I accessed our production environment with 4 replicas and got a 502 from the network. I investigated and it seems the server was running normally, no crashes or anything.

However, in the HTTP logs I see the message "Retried single replica" 
What does this mean?

Could you please clarify?

Thank you.
