Dashboard frozen for one line, Server Status shows the channel in "Error"

[ProcessPilot]

Since this morning, the OEE values for Line 3 are not moving, while the other lines are fine. The machine is running. I opened the Server Status page and in the Channels list the Line 3 channel shows State "Error" and Last read is about four hours ago. The Last error column has a short message about a timeout.
Electricians replaced a switch in the Line 3 panel yesterday evening. Is there a way to get the channel back without restarting the whole server? And what else on this page should I be looking at?

[Technical Support]

The Server Status page is exactly the right place to start, and a timeout right after network work in the panel points strongly to a network issue rather than a Proveris problem.
1. Check the network path
From the Proveris server, ping the PLC's IP address. If the switch was replaced, check whether the PLC port is in the right VLAN, whether the cable is in the right port, and whether any IP was changed. The Address column on the channel shows exactly which IP and port Proveris is trying to reach.
2. Watch the channel state
After the network is fixed, the channel normally recovers by itself. Watch the State change from "Error" to "Connected" and the Last read time refresh. You don't need to restart the server for this.
3. Use the engine log
Further down, Engine log (live) shows the communication messages. Filter with "Warnings + errors" and search for the channel name to see when the errors started and whether they're still happening.
4. Restart only if needed
If the network is fine and the channel stays in Error, use Restart at the top of the page. A Developer account is needed for this. Restarting interrupts data collection for all lines briefly, so do it between shifts if possible.
Other useful parts of the page
- License: mode, tag limit, user limit and expiry. If the license is invalid, communication and OEE don't run at all.
- Last configuration reload: confirms that recent changes in tags or machines have been loaded.
- Connected users and Active alarms.
