login agent failed

One of our run-time resource today failed to login by using login agent. The error message is : 信号灯超时时间已到. This Chinese may be saying "The semaphore timeout period has expired". How can I address this issue?

Hi Eric it's an article in this Knowledgebase https://portal.blueprism.com/customer-support/support-center#/path/

This is a cut & paste from the article but it contains more links to more articles, so if you can't reach these either, it may not be helpful:

How do I fix "The semaphore timeout period has expired" error when using Login Agent functionality?

When using the Login Agent component it is possible for the machine to not respond quickly enough and report the following error in the Session log:

"The semaphore timeout period has expired".

This error is usually an indication that the Login Agent VBO has timed out waiting to connect to the credential provider's named pipe.

There can be multiple causes for this but the most common are listed below:

Named pipes are blocked by policy or security software.
The policy requiring the SAS is still enabled
Another custom credential provider is loaded displacing the Blue Prism credential provider
The customer is attempting to use Remote Desktop with Login Agent

How to resolve this issue:

Enable the Credential Provider logs to help identify the root cause.

If is the issue is caused by named pipes being blocked by policy or security software, then please see the article How do I fix "Named pipe handle is invalid" error when running Login Agent if the Group Policy settings are incorrect?.
If the issue is occurring because the policy requiring the SAS is still enabled, then review your Group Policy settings to ensure that your CTRL+Alt+Delete to login is disabled. You can read more about this in the article: How do I configure Login Agent Group Policy settings?
If the issue is caused by attempting to use Remote Desktop with Login Agent then please see the article: How do I fix "Named pipe handle is invalid" error when running Login Agent if Remote Desktop has been used?

Also see the following articles for further information and solutions:

You may wish to involve your IT department to assist with such investigations.
