webMethods Knowlegebase : HTTPS Websockets session disconnects error 1006 and reconnects (1789138)

Troubleshooting


Problem

Environment: UM (Universal Messaging) server v10.1 Fix 4, Javascript client v10.1 Fix 3

Problem appears in all browsers tested, Edge, Chrome, and Firefox.

It only occurs on HTTPS connections (no client cert required).

HTTP works as expected.

Problem: Websockets connections that are created using the JavaScript library nirvana.js disconnects and reconnects approximately every 10-12 seconds.

Analysis: the JavaScript client logs show the following:

"[Transport] Received Driver OnError Callback with error: [object CloseEvent] Error Code : 1006"

This seems to be a websocket-specific error code meaning the connection was closed abnormally (locally) by the browser implementation.

But it's not clear if this is provoked by some other problem in UM or is the real cause.

The nirvana.log file shows the disconnect a second before the client log.

Nirvana.log shows the following:

"[Mon May 07 09:33:12 CDT 2018] [ClosePool:0] [com.pcbsys.foundation] - IO : [10.36.17.60:58733] Closing connection with queue size = 0

Web client log

This reproduces with a simple JS (Java Script) web page in environment with HTTPS.
