Hi everybody,

Is it necessary to have a shipping provider ? Is there a basic free plugin or we must develop or pay one ?
Before checkout, I get error "Shipping rate computation method could not be loaded". I don't know if it's linking to Shipping Provider.

Thanks

It's ok now... I have just to build Plugin :)

Not work, I get always "Shipping rate computation method could not be loaded"

Hi,
Please go to Admin -> Configuration -> Shipping -> Shipping providers - and check as active

Krzysztof

Thanks Krzysztof, it was this problem also. But now, if I test on local address ip it's ok but through my HAProxy, I can't pass to mode shipping. I have not error in code on explorer.

Laurent,

Can you check the System -> Log?

Hi Patryk,

For solution, I have

With HA PROXY, the good config for app settings.json is :

{
  "Hosting": {
    //Set to "true" the settings below if your hosting uses a load balancer. It'll be used to determine whether the current request is HTTPS
    "UseHttpClusterHttps": false,
    "UseHttpXForwardedProto": true,

    //Use the setting below if your hosting doesn't use "X-FORWARDED-FOR" header to determine IP address.
    //In some cases server use other HTTP header. You can specify a custom HTTP header here. For example, CF-Connecting-IP, X-FORWARDED-PROTO, etc
    "ForwardedHttpHeader": "",

    //Use a reverse proxy server - more information you can find at: https://docs.microsoft.com/en-US/aspnet/core/host-and-deploy/linux-nginx?view=aspnetcore-2.1
    "UseForwardedHeaders": true
  },

Without this, I have bug in checkout and cannot pass to payment step. GrandNode return to cart page.
