I am trying to do Lora OTAA activation on my LoPy4 node. A few days back OTAA was working all fine, but now it is not working. LoPy4 is sending the join request to loraserver, which are not accepted by the server. I have attached the screenshots of Debug logs. It is not connecting kept from 2-3 hrs.
Please help why these OTAA join requests are not accepted.
There are multiple topics already covering OTAA issues. E.g. Debugging device activation OTAA issues (https://forum.loraserver.io/search?q=otaa%20failed).
