Hi Axel,

Thank you for the reply. I have pasted some of my nginx.conf file below. Can you conform if i'm setting proxy_next_upstream in correct location please?

Also, is there a way to have fail_timeout increment per fail? i.e if it failed once try again in 30 secs as it might be minor issue, then if that fails try a again in 2 mins, then 4 mins etc?
