Hi @Liam , I have same type of issue like this, my project (base on remix template) working good before, but now when after run “npm run dev” then click the generated app preview URL, the remix server console output “FetchError: request to https://hellonick.myshopify.com/admin/api/2023-10/graphql.json failed, reason: Client network socket disconnected before secure TLS connection was established” error, there is some log as below:
I believe it’s occured during “authenticate.admin(request)” function call.
package.json info:
@shopify/app: V3.53.0
@shopify/cli: V3.53.0
@shopify/shopify-app-remix: V2.1.0
@shopify/shopify-api: V8.1.1
And, did Shopify recently changed some basic network service providers or not ? if yes, the issue maybe it’s related to it.
