mDot FOTA fails with packet dropped warning message on port 200.

Below is part of the logs from the mdot and I had kicked of a FOTA transfer and I see a warning message in the logs indicating a packet received on Port 200 was dropped and the FOTA progress on the conduit indicated the transfer failed. Any ideas as to why that would be the case and how can I resolve it. Also the conduit is on version 5.2.5 and the mdot firmware is using the latest mDot API.

I fixed this issue, I wasn’t initializing the fota instance with the mdot instance and this resolved it. I am running into other fota issues, I will open a ticket instead of waiting for someone to respond to my forum questions.

Thanks,
Ajay
