WCF Timeout Error

Question

Error is:

The request channel timed out while waiting for a reply after 00:00:59.9339962. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout.

<system.serviceModel>
      <bindings>
        <basicHttpBinding>
          <binding name ="IncreaseTimeOut" sendTimeout ="00:25:00"></binding>

      </bindings>

Are you really waiting around 60 seconds or are you receiving this exception message immediately after sending the request? — Marc

you need to provide more information. i assume sometimes in the client side you receive time out. this may cause by so many reasons. here is some example:

1- bad network connection.

2- firewall block your website.

3- WCF concurrent connection configuration or max connections limit. you can increase the connection limit in your web.config like this:

<system.net>
<connectionManagement>
  <add address="*" maxconnection="500" />
</connectionManagement>

the default value is 2. for more information you can read this: scale up WCF service
