[Çözüldü] WSUS - Error: Connection Error

Merhaba;

Windows 2012 R2 üzerinden WSUS yapılandırması yapıldı. Kullanıcılar için policy oluşturuldu. Güncellemeler belirli saatlerde yükleniyor.

Fakat bazı update seçeneklerine girildiğinde örneğin DRIVERS bir süre bekledikten sonra Error: Connection Error hatası almaktayım.

Hata içeriği;

The WSUS administration console was unable to connect to the WSUS Server via the remote API.

Verify that the Update Services service, IIS and SQL are running on the server. If the problem persists, try restarting IIS, SQL, and the Update Services Service.
