Hi,

I am working on an mqtt gateway and regarding where I work (is it alright if we can talk about this in private smile ). I have attached the pcap file that I captured using tcpdump here. Please let me know if there is anything else you need from my end. Just wondering, could this issue be related with incompatibility between cipher suites available on both ends?

Hi,

I am trying to use wolfssl on an embedded system (esp8266) to connect to thingsboard (mqtt over tls).
Unfortunately, I get a -308 error at the end of the handshake after cipher suite change.
I am not sure what is causing Embed Send to fail.

You can find the error log attached.
