I am using Magento 2.3.6 and have installed Amazon Sales Channel 4.4.0, I have added the Production API Key and Production Private Key under Magento Services but I get this error "Unexpected network error", can anyone explain what causes this error?

enter image description here

Click Add Amazon Store and I get this error:

enter image description here

Browser Console: GRAPHQL ERROR: Error: GraphQL error: Internal server error https://cdn.amazon.channels.magento.com/4.4.0/static/js/components/HelperFunctions/GQLErrorHandler.tsx

import { ApolloError } from 'apollo-client';

interface MagentoNetworkError {
  name: string;
  response: {};
  statusCode: number;
  result: {
    ajaxExpired: number;
    ajaxRedirect: string;

 If Magento is open in 2+ tabs, and the user signs out in one of them, all
 the other sessions will also be terminated. All GQL queries & mutations will
 return a Network Error that follow the pattern in the interface above. 
 If that's the case, display a toast
 that will not go way. If it's any other error, then just display whatever 
 custom message was passed in. 

export const GQLErrorHandler = (error: ApolloError | undefined, message?: string) => {
  let networkError = (error?.networkError as unknown) as MagentoNetworkError;

  if (process.env.NODE_ENV !== 'production') {

  if (
    networkError &&
    networkError.result &&
    networkError.result.ajaxExpired &&
  ) {
    errorToast(`Your session has timed out.`, {
      actionLabel: 'Sign in',
      onAction: () => {
      timeout: 0,
  } else if (error) {
    let errorMessage = message ?? 'Unexpected network error, please try again later.';
  console.error('GRAPHQL ERROR: \n ' + error);
