I have tried changing the protocol from web services to web HTTP and created web_custom_request.It seems all good for me now.Not getting error.May be this is best workaround for me now.

Hi,

Do you see HTTP/2 headers in your replay log (Advanced trace)?

Could you, please, send me default.cfg file from your script?

I just checked this key in web services script and it disables HTTP2.

Leonid.

HI Leonid,

Tried adding EnableHTTP2=0 in default.csg. getting the same error.

Please, add this line under[WEB] section in default.cfg file:

EnableHTTP2=0

Regards,

Leonid

Hi,

Thanks for the reply.

We do not have internet protocol options available for web service protocol to disable HTTP2. Could you please suggest any workaround do we have for this. 

Also i tried providing different chip sets which are related to HTTP2. But nothing is working out.

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.

Hi,

In case using HTTP/2 protocol is not required in your test, you can disable HTTP/2 features in Runtime Settings  (Internet Protocol > Preferences > HTTP -  uncheck option "Enable HTTP/2 features"). 

Replay will use the mentioned cipher agreed in SSL handshake without switching to HTTP/2.

Otherwise you can choose different cipher. Ciphers that are not supported by HTTP/2 are mentioned in LoadRunner documentation.

Adding more to the above article,I am using Web_service protocol for Post API Calls.

script was working fine without any additional SSL details.
