Hi @Iakshan,
I’m happy to see that you are searching the cause and I’m sure you’ll find it soon.
My investigations let me think that it might be a similar reason as posted here:
At least if I add a ‘_connected = false’ in the WiFiClientSecure::stop() routine, my application continues to work after a failed upload.
(However it may be that the true cause is somewhere else)
Best regards
