Troubleshooting staging
This page describes how to resolve the most common errors that you may encounter when using staging.
Failed staging task synchronization
Problems typically occur when the synchronization of staging tasks fails. To check your system for failed staging tasks and
identify the type of error:
1. Open the Staging application on the source server.
2. Look for staging tasks that have the Failed status in the Result column.
3. Click Failed to view the error message details in the Synchronization log dialog.
HTTP status 404: Not Found error
Error: "Synchronization client error: Exception occurred: The request failed with HTTP status 404: Not Found."
Not found errors occur in the following cases:
If the staging service URL is set incorrectly for a target server.
When attempting to stage page attachments or media library files that are too large.
Open the Staging application on the source server where the problem occurs.
On the Servers tab, edit all registered target servers.
Check that the Server service URL of each server is correct, including the domain and virtual directory (if necessary).
If you are using staging to transfer very large files, see Staging large files.
Parent node does not exist
Error: "SyncServer.ServerError: Exception occurred: [SyncManager.UpdateDocument]: Parent node does not exist, please
synchronize parent node first."
Occurs when attempting to synchronize a page whose parent or other ancestor page does not exist on the target server. Can also
occur if the parent or ancestor page was created manually on the target server outside of the staging process (i.e. when the
GUIDs of the pages do not match on both servers).
Synchronize all ancestor pages of the required page first. If your servers have inconsistent page GUIDs, you may need to delete
the ancestor pages on the target server and synchronize the entire section from the source. You can use the Synchronize
current subtree action on the Pages tab of the Staging application (see Synchronizing the content).
If possible, always avoid manual creating of pages on the target server for sections where you plan to deploy pages via staging.
The correct approach is to transfer all pages via the staging service.
Incorrect staging service password
"Synchronization client error: Exception occurred: Microsoft.Web.Services3.Security.SecurityFault: The security token could
not be authenticated or authorized. ... The computed password digest doesn't match that of the incoming username token."
Occurs when the server password on the source instance does not match the password configured for the staging service
settings on the target server.
"Synchronization client error: Exception occurred: System.Web.Services.Protocols.SoapException: Server was unable to
process request. ---> System.Exception: Missing X509 certificate token, please check authentication type "
Troubleshooting staging
Occurs if the server on the source instance is configured for user name and password authentication, but the target server uses
X.509 authentication.
"Synchronization client error: Exception occurred: [X509ClientOutputFilter.SecureMessage]: Unable to obtain server security
token ID."
Occurs if the server on the source instance is configured for X.509 authentication and the target server does not have valid X.509
Troubleshooting staging
1. On the source instance, open the Staging application and edit your target server on the Servers tab.
2. On the target instance, open the Settings application and select the Versioning & Synchronization -> Staging category.
3. Verify that the target server on the source instance and the Staging service settings on the target instance have matching
authentication settings, including:
The authentication type (User name / password or X.509)
The User name and Password (for User name / password authentication)
The Client key ID and Server key ID (for X.509 authentication)
Troubleshooting staging
Invalid service URI
Error: "Synchronization client error: Exception occurred: Invalid URI: The format of the URI could not be determined."
URI format errors occur if the protocol (for example http://) is missing in the staging service URL of your target server.
1. Open the Staging application on the source server where the problem occurs.
2. On the Servers tab, edit all registered target servers.
3. Make sure the Server service URL of each server includes the correct protocol. For example: http://www.targetserver.co
SOAP header security not understood
Error: "Synchronization client error: Exception occurred: System.Web.Services.Protocols.SoapHeaderException: SOAP header
Security was not understood."
Can occur in certain environments. This is a general error related to .NET and WSE.
Add the following to the <system.web> section in the web.config file on the target server:
<add type="Microsoft.Web.Services3.Description.WseExtensionImporter,
Microsoft.Web.Services3, Version=, Culture=neutral,
PublicKeyToken=31bf3856ad364e35" />
<soapServerProtocolFactory type="Microsoft.Web.Services3.WseProtocolFactory,
Microsoft.Web.Services3, Version=, Culture=neutral,
PublicKeyToken=31bf3856ad364e35" />
<add name="HttpSoap"/>
<remove name="HttpPost" />
<remove name="HttpGet" />
Timeout expired
Error: "The timeout period elapsed prior to completion of the operation or the server is not responding."
Timeouts may occur when synchronizing a very large number of staging tasks within a single operation. The default timeout
interval is 180 seconds.
Either synchronize the tasks in smaller batches or increase the timeout interval. To increase the interval, add the CMSStagingSer
viceTimeout key to the configuration/appSettings section of the web.config file on the source server and set the value:
Troubleshooting staging
<add key="CMSStagingServiceTimeout" value="300" />
HTTP status 413: Request Entity Too Large
Error: "Synchronization client error: Exception occurred: The request failed with HTTP status 413: Request Entity Too Large."
Can occur when synchronizing pages over HTTPS.
Increase the uploadReadAheadSize attribute to raise the maximum number of bytes a Web server will read into a buffer and pass
to an ISAPI extension.
Note that it is not recommended to set the value to the maximum (2147483647) due to security reasons. Instead, determine the
smallest value that the server should be allowed to read into a buffer and use that instead. The default value is 49152 bytes.
For example, the following appcmd.exe command changes the uploadReadAheadSize value to 245760 bytes.
appcmd.exe set config "Default Web Site"
-section:system.webServer/serverRuntime /uploadReadAheadSize:"2147483647"
Incorrect relationships between objects after staging
Problem: Bindings (relationships) between objects disappear after synchronizing changes from a different staging instance.
Such problems can occur because staging includes all child objects and bindings when synchronizing most objects.
For example: A role is not assigned to any users in the development environment, but to 100 users on the target production
server. If you synchronize the role object through staging, the users are removed from the role on the target server.
Solution: Ensure that content and objects is mirrored and consistent across all staging environments.
Problem: Custom fields that store ID values (for example object selectors) point to different objects or are empty after
Content staging cannot ensure that objects and pages have the same ID values after being transferred to a different
environment. However, the synchronization process preserves GUID values.
Solution: Use fields with the Unique identifier (GUID) data type if you need to safely identify pages or objects across multiple
staging environments.
Problem: Objects are assigned to the wrong site after synchronization on instances with multiple sites.
Solution: Make sure that the service URLs set for target servers on your source instance contain the domain names of the
correct sites. Each site's servers must use the domain name of the matching site on the target instance.
Troubleshooting staging
Synchronization fails when using SSL
You may encounter problems when synchronizing staging tasks over a secured protocol (SSL). By default, the staging service
only accepts certificates issued by a trusted certification authority.
To configure the system to accept all certificates, including self-signed, add the CMSStagingAcceptAllCertificates key to the con
figuration/appSettings section of your web.config file:
<add key="CMSStagingAcceptAllCertificates" value="true" />
