@MMaiero I need your help troubleshooting this issue. The PR has an issue on MQTT tests using SSL. You may have a look at the CI log Caused by: org.eclipse.paho.client.mqttv3.MqttException: MqttException
Caused by: javax.net.ssl.SSLHandshakeException: No name matching localhost found
Caused by: java.security.cert.CertificateException: No name matching localhost found |

Hi, did you have a look if this is a known issue of version 1.2.5? |
Nope. Versione 1.2.1-k2 is a fork: Kura is actually using a modified version of Paho as reported in that PR. We do not encount any kind of issue in our test on Kura 4.1.3 due to the fact we're not using SSL yet. Hopefully I will port the same fixes on 1.2.5, releasing a forked version for you if the code base is not so different from 1.2.1 I was not aware of this fork, sorry |

Yes, we have created that fork due to some unresolved issues in paho and their threading model that would leave dangling threads over time. I think there is still an issue in their repo that I have open-end and probably also a PR. But those were never addressed by the pho committers. But the issue seems related to tests failing with 1.2.5 that were previously passing with 1.2.1 (independently from the fork). So that's why I have asked the question. |

A real bad day for me.. I have deleted my forked kura repo inadvertently :( I will come back with a new PR when I will have a fixed version of embedded Paho too....so sorry :( |
