Starting with the release of Strategy ONE (March 2024), dossiers are also known as dashboards.
Troubleshooting:
This article outlines a scenario where setting up Strategy HyperIntelligence Chrome extension results in receiving a "connect timed out" error when working with Cards.
When interacting with Cards in Strategy Workstation, a "Failed to initialize Card" error appears with the details saying, "connect timed out".

This does not occur when interacting with Dossiers or working with Datasets.
Check the Workstation logs for an error that is showing a 500 status code and that also mentions a RestApiError. The error should look similar to below:

On Windows, Workstation logs can be found at
C:\Users\<UserName>\AppData\Local\Strategy_Inc\log\Workstation.log
~/Library/Application Support/com.Strategy.Workstation/Strategy Workstation.log

Library server logs can be found in
StrategyLibrary/WEB-INF/classes/logback.xml
<property name="LOG_HOME" value="logs" />
For the HyperIntelligence browser extension, the Library Server connects to the REST Server running on the same machine as the Intelligence Server. This REST Server uses a different port than the Intelligence Server to communicate with the Library Server. Another port must also be opened to allow the Library Server and REST Server to communicate.
Open port 34962 in addition to port 34952 on the machine running the Intelligence Server. This will allow the Library Server to connect to the REST Server on the Intelligence Server machine. Bear in mind that both those ports are the default port values. If they were changed during the Intelligence Server configuration then a different port needs to be opened. The port 34962 only needs to allow the Library Server machine to connect to it.
Note: Please also ensure the host is added to the hosts file as you may see other errors without that configuration. See this article for more information: Solving Errors like "Failed to initialize Card" While Connecting to the Host Environment.
