Hi @lenzarda, 20 seconds is a long time for a handshake! To be clear, are you saying that sometimes the handshake completes quickly, sometimes slowly, and sometimes not at all (how long do you wait for it?) It looks like you have a timeout set on the mbedTLS connection (which is good), can you confirm? Are you able to post the exact code you're using somewhere? Do you think the TCP connection may be quite lossy? Is there any possibility of getting a packet capture from either the WiFi router or the server side? Angus |

Hi @lenzarda, I tried to reproduce this yesterday on the current IDF master branch by modifying the HTTPS example to point to the same server you are using, and to fail if a handshake takes more than 10 seconds. Over 1000 requests with no failures. The code I used is here: https://gist.github.com/projectgus/4d6b8dd7b1249e01f96f9fd796543b46 There have been some improvements and fixes to mbedTLS since this was reported, so it's possible this issue has been resolved. Otherwise, is there anything you can provide to help us to reproduce? A wireshark/tcpdump packet capture of a failing session (from either the client or server end) would be very helpful. Thanks, Angus |

Thanks for your support! It works now. You can close this ticket. |
Hi
I am using a modified version of the example https_request with esp-idf latest commit 843159b.
As recommended in #630 the "Enable hardware MPI (bignum) acceleration" is not enabled.
mbedtls_ssl_handshake works not very often. In the majority of the runs I get the following logs.
Any idea on how to fix this?
It is really blocking for me.
Thanks
