Using HTTP protocol I am trying to communicate with server but recently I am getting an error in spi_data_read as "Failed data response read". Strange thing is, I do not encounter this error when I run the code in debug mode, in debug mode it runs smoothly. When I start without debugging, above error is encountered. This code used to work earlier. I tried running the code on two Atmel boards but the error still persists.

Don't know the SAMD21 or any of the SAM chips, but my first question is: what is using SPI on the server? Is there, perchance, an SD or uSD card? Or maybe an NV serial memory? Or, something else?
