    TLS Handshake Error on Azure Event Hub




      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.
