Synthetic Errors on node Join request - ok 24 hours ago

hi everyone. I have been working on refining the code for a project and the node (one of 20) was working fine yesterday but today will not connect with regular synthetic console messages including

{
  "time": "2023-12-13T17:10:28.473Z",
  "name": "synthetic.status.reconnected",
  "isError": false,
  "isSynthetic": true,
  "unique_id": "synthetic.1702487428473"
}

and

{
  "time": "2023-12-13T17:11:56.473Z",
  "name": "synthetic.error.unknown",
  "isError": true,
  "isSynthetic": true,
  "unique_id": "synthetic.1702487516473",
  "data": {
    "error": "Error: [object Event]"
  }
}

please ignore the times as these normally are occurring within 6 seconds of each other and when my node 20 is trying to join. Other nodes are still reporting but I have been developing on Node 20 and so there have been a lot of Join messages in the last 24 hours but I was not aware of those taking up data time? Other nodes still seem to be reporting ok - would love some advice as I am in the field in Costa Rica and have limited internet access - thanks everyone.

Cheers, Garth

How often is your node trying to join?

What is the MCU / radio / firmware?

What version of LW are you using?

And most important of all, what is the RSSI & SNR of the Join Request?
