Client Object Model - The remote server returned an error: (403) Forbidden.

Question

Hello,

•  I write the following code in console application to read data from list by client object Model :

            ClientContext context = new ClientContext("servername/sites/Dhofar/en-us");
            List list = context.Web.Lists.GetByTitle("MenuList");
            context.Load(list);
            context.ExecuteQuery();
            Console.WriteLine(list.Title);
            Console.ReadKey(false);

• I got an exception "The remote server returned an error: (403) Forbidden." on line "context.ExecuteQuery()"
• I run the console application the same server that has a SharePoint.

     How Can I solve this problem?

Answer 1

This would indicate you either do not have permissions to the site, or the list.

Hi,

According to your post, my understanding is that you got forbidden error when retrieve data using client object model.

Per the error, the issue may be related to the permission issue, you can check with the following steps.

First, you can check the permission in the site or list, or use the admin account to check whether it works.

Second, you can use the a credential to check whether it works as below.

           

 ClientContext context = new ClientContext(siteURL);


            //specific user

            NetworkCredential credentials = new NetworkCredential("Username", "Passworkd", "Domain");

            context.Credentials = credentials;

                           List list = context.Web.Lists.GetByTitle("List1");

            context.Load(list);

            context.ExecuteQuery();

Thanks & Regards,

Jason

Is it plausible that you are experiencing the error "HTTP 403 Forbidden" in SharePoint when trying to run the code? Do you have the proper credentials? If not, were they inadvertently blacklisted?
