If you enable Data Services to publish MQTT with Sparkplug payloads, it's possible that an unreliable network connection may create a state where an MQTT client indicates that data from your groov EPIC or groov RIO is stale even though groov Manage indicates that Data Service is running.
If you’re experiencing stale data and groov Manage indicates the Data Service is running, then check the most recent entries in the log. Entries similar to the following may indicate that the stale data is caused by this issue:

This issue may also be present if you are publishing string payloads or you are using OPC UA.
Do one of the following:
- Manually restart Data Service:
- From the groov Manage Home page, click Data Service.
- In the Data Service Runtime field, click Disable.
- Wait for the Data Service field to report Disabled.
- Click Enable.
- Cycle power on your groov EPIC/RIO.
