Hi there @agus.halim,

I tried replicating your setup at my end and a quick fix would be to change the Health check from HTTP to TCP. That way your load balancer would check if your Droplets accept connections on port 80 and if so it would consider them as healthy.

Hope that this helps!

Hi Bobbyiliev,

i had try change the port forwarding rule from HTTP to TCP port 80. no luck. still offline.
and if i type my domain which already point to Load balancer IP Address it also cannot load anything. but if i change the A record from Load balancer to my ip server directly it working perfectly.
i also tried to downgrade my OS from OS Ubuntu 20.04 to Ubuntu 18.04 and results still the same.

Any ideas what could make this wrong?

appreciate & thanks
Agus

  • Hi there @agus.halim,

    Can you please make a screenshot of your Loadbalancer configuration? Make sure to hide any sensitive information.

    On another note, if you visit your Droplet’s IP address directly, what is the result that you get?

    Regards,
    Bobby
