Getting "Connection Reset" error instead of 401 on multipart HTTP

10.15

Hi,

I am making a multipart HTTP call with a Bearer Token. When I use the right token I don’t have any problems. I can send a pdf file with that call.

My problems start if I use the wrong Bearer Token. Everything works normally if I send a request with the wrong Token via Postman. I can see the HTTP code as 401, the response as JSON, and also header values without an issue.

PostmanResponseHeader
PostmanResponseHeader2132×537 54.6 KB

When I make the same request from 10.15 webMethods server via “pub.client:http” it throws “com.wm.net.NetException: [ISC.0064.9306] Connection was closed during read” or “com.wm.app.b2b.server.ServiceException: java.net.SocketException: Connection reset” error.

I changed the log level to “Trace” for Integration Server and attached the related piece of logs here.
server.log (11.1 KB)

As I understand from the logs, I am getting 401 in the first place but then the webMethods server makes another call, this time it uses NTLM for authorization then it gets 401 again but this time I see WWW-Authenticate: NTLM in the response header and probably it causes the issue.

I am unsure why it retries after it gets 401 and where this NTLM is coming from. I can provide further info if needed.

Are there any suggestions to solve this?

Many thanks in advance.

Your query is not pretty clear, but check out this setting if it makes some difference.

watt.net.http401.retryWithoutCookie

Controls whether Integration Server retries HTTP requests without a cookie header. Set the parameter to false to prevent the pub.client:http service from retrying a request without a cookie header when Integration Server receives HTTP 401 as the response. The default is true.

Note:
The watt.net.http401.retryWithoutCookie parameter is introduced for PIE-76895 in IS_10.15_Core_Fix1.

Hi Sandeep,

Thanks for your answer. I set “watt.net.http401.retryWithoutCookie” as false but the result is the same. I also set false to " watt.net.http401.throwException" to disable getting exceptions after I got 401 but it also didn’t help.
