If the node is running correctly and you’ve verified it’s best block is the same as the one on telemetry then you should be fine.
The farmer only has to plot once since it’s not really “stopped” it’s just done with its task for the moment
Look at logs of the node, it must be downloading something. Segments are plotted only when new history is created, which happens frequently during initial sync, but later only once in a while (judging by logs, you’re not fully synced yet).
The only explanation I have for this is that you have a very slow network connection to other peers on the network. We already reduced requirements for Gemini 2a, but you are still expected to have ~10Mbps reliable connection. Not just to local servers in your country, but to other participants on Subspace network all around the world.
