Duplicates: U4-5728

Logfiles on one of our sites keep getting swamped with the following errors after upgrading to version 6.2.4. It's a '''non-load balanced''' site running on '''HTTPS''' on a Win2008R2/IIS7 server, umbracoUseSSL is set to true in the web.config.

2014-11-19 16:57:52,204 [21] ERROR Umbraco.Web.Scheduling.ScheduledPublishing - [Thread 47] An error occurred with the scheduled publishing System.Net.WebException: The operation has timed out at System.Net.WebClient.UploadDataInternal(Uri address, String method, Byte[] data, WebRequest& request) at System.Net.WebClient.UploadString(Uri address, String method, String data) at Umbraco.Web.Scheduling.ScheduledPublishing.Start(ApplicationContext appContext) 2014-11-19 16:58:22,203 [21] ERROR Umbraco.Web.Scheduling.KeepAlive - [Thread 116] Error in ping System.Net.WebException: The operation has timed out at System.Net.WebClient.DownloadDataInternal(Uri address, WebRequest& request) at System.Net.WebClient.DownloadString(Uri address) at Umbraco.Web.Scheduling.KeepAlive.Start(Object sender) I've checked out the following similar issues/posts, and experimented with the suggested solutions, but to no avail:

https://domain.com/umbraco/RestServices/ScheduledPublish/Index returns a 404 status. I have 2 custom scheduled tasks in place, and these work without any issues.

I have also configured the following redirect in the UrlRewriting.config:

Disabling this rewrite doesn't have any effect on the errors.

Any help would be appreciated.

I have tested the workaround which was mentioned by Sebastiaan in the following forum post:


Adding this setting to the web.config of our version 6.2.4 website didn't work. Both errors were still being logged.

I've added a patch for 6.2.4 in U4-5728.

@sebastiaan Has the patch you provided for version 6.2.4 also been included in version 6.2.5?
