    Hi 

    Actually it's not a issue of LR.

    Normally the root cause is that your server selected "http2" but chose a cipher which is not supported by "http2".

    LR supports both "http1.1" and "http2".

    When connecting server, LR will say both "http1.1" and "http2" are supported, and list a default cipher list(contains many ciphers) by a "ClientHello".

    (LR don't know which http version or cipher your sever will choose, so just put the default list into it)

    Then wait your server answer a "ServerHello" to choose the http version and cipher.

    If your server choose the "http2" with a wrong cipher, you will get this error.

     

    The simplest solution is "disable http2" as Leonid said, if you really don't need it.

    If you really need http2, you can try another solution. Set a cipher (or a cipher list) by web_set_sockets_option, which is supported by http2.
