 !!!note
     If you pause the debugger, and happen to forget about it, the agent will automatically kill itself and restart because it will think that a thread is stuck. Default debugger timeout is 10 minutes, you may find a log entry saved to disk saying "Microstack Thread STUCK", or something similar.
 
+### Troubleshooting Agent connectivity
+
+If an agent keeps disconnecting and reconnecting, add this line to the "settings" section of the config.json:
+
+```
+"agentping": 30
+```
+
+This will cause MeshCentral to "ping" the agent every 30 seconds and the agent to respond with a "pong" each time. That usually solves the issue however, it does generate more traffic. If that works, you can remove the line and try this line instead:
+
+```
+"agentpong": 30
+```
+
+This will cause MeshCentral to "pong" the agent every 30 seconds, the agent will not respond. This usually fixes the issue, but you have half the traffic. I would also increase the time like:
+
+```
+"agentpong": 90
+```
+
+This is the best, you have one way traffic to all agents every 90 seconds. The larger the number you can get away with the better.
+
+If you ever get the same problem but on the browser side, you can also use one of these:
+
+```
+"browserping": 30
+"browserpong": 30
+```
+
+Same idea, browser side instead of agent side.
