read error: "end of file", debian 16.04
Hi,

no matter what settings I use, both on the miner side and proxy side, I keep getting "end of file" error every 2 minutes. Both connections are working good and I've also tested the connection from the proxy server to the mining pool. There are no lost packets.

on the proxy side I have the config.json,

            "rig-id": null,

        }
],
    "retries": 2,
    "retry-pause": 3,
    "reuse-timeout": 1,

....
}
=============================================

both configs have worked good before and I'm not sure why I have this problem. I keep getting the read error: "end of file" ~ every 2 minutes.

I used debug on and it says

read error: "end of file"
[2020-03-25 12:50:59.706] [ ] state: "connected" -> "closing"
[2020-03-25 12:50:59.706] [ ] state: "closing" -> "unconnected"
[2020-03-25 12:50:59.707] [ ] state: "unconnected" -> "reconnecting"
[2020-03-25 12:50:59.707]  net  no active pools, stop mining


How can I fix this problem?

Thank you!
