we are making MQTT client application that should connect to Amazon AWS server. But after my application sends:
I got an error:
ERROR: Failed to resolve name<CR><LF>
Temporary solution was to find real IP of server using whois in my console and put is instead of server address. Now i can connect but i want to use real server address in application if possible.
Moreover, I'm sure that DNS address is correct because we are using time-d.nist.gov service to get current time/date without a problem.
Maybe the address string is too long for module? (We are using latest firmware for SPWF01 that is available for download v3.5)
