Prerequisites

  • What is your product version? 10.5
  • What is your product type (Angular or MVC)? Angular
  • What is product framework type (.net framework or .net core)? .NET Core

After updating to v10.5, we are getting a lot of CORS issues. For now, we have updated our cors code as follows:

services.AddCors(options =>
{
    options.AddPolicy(DefaultCorsPolicyName, builder =>
    {
        builder
            .SetIsOriginAllowedToAllowWildcardSubdomains()
            .AllowAnyOrigin()
            .AllowAnyHeader()
            .AllowAnyMethod();
    });
});

But now, we get error in SignalR requests. Can someone please help?

Our original CORS config in appsettings:

    "CorsOrigins": "https://*.primepenguin.com,http://primepenguinapp.trafficmanager.net,http://localhost:4200,http://localhost:9876"

    Hi @ajayak

    Did you check server side log file for any related errors ? I don't remember a change related to CORS in the latest version. Probably the reason is something else.

    @ismcagdas, I cannot find anything useful in logs. It is only related to CORS.

    @ismcagdas, I have reverted the changes that were made to cors. Can you help me in fixing my CORS origin? Our frontend app is not able to access backend. Current config:

    "CorsOrigins": "https://primepenguin.com,https://*.primepenguin.com,http://primepenguinapp.trafficmanager.net,http://primepenguinservice.trafficmanager.net,https://app-eu.primepenguin.com,https://app-fr.primepenguin.com,https://localhost:4200",

    Error:

    `app.primepenguin.com/:1 Access to XMLHttpRequest at 'https://service.primepenguin.com/AbpUserConfiguration/GetAll?d=1633500363976' from origin 'http://app.primepenguin.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

    Updated the config as below:

    https://app.primepenguin.com,https://app-eu.primepenguin.com,https://app-fr.primepenguin.com,http://app.primepenguin.com,http://app-eu.primepenguin.com,http://app-fr.primepenguin.com,https://*.primepenguin.com,http://primepenguinapp.trafficmanager.net,http://primepenguinservice.trafficmanager.net
    

    And our app finally works correct now.
