    TLS Handshake Error on Azure Event Hub

    mahe_2162211

      Hi,

       

      can you guys check out if you can connect to the Azure Event Hub over TLS connection? Today all our WICED modules stopped sending data to the hub - very critical issue.

       

      After investigation it seems that the error coming out of ssl_handshake_client_async is 4294966880 = FFFFFE60 = -0x01A0 = TLS_ERROR_X509_CERT_UNKNOWN_SIG_ALG. It seems that Microsoft updated their certifcates today.

       

      Azure Event Hub for test:

           host: seltronhomeweu0000stg.servicebus.windows.net

      We are using version 2.4.1. and we have also reproduced this issue on 3.1.2.

       

      Thanks,

      Matej
