java.net.SocketException

tip

Upgrade your docker-selenium

tip

Probably there is a bug in TestNG Eclipse plugin (6.8.6.20130607_0745), try an other version (e.g. 6.8.0.20121120_1820)

tip

before running my test in debug mode, i open the debug view, and remove some breakpoints (such as some remaining on NullPointersExceptions, and Sockets)

tip

Try removing all the breakpoints (even if breakpoints are disabled the problem still occurs, yes even if both disabled entirely and piecewise).

tip

There is a known issue between TestNG 6.4 and IDEA, the next EAP will fix this but in the meantime, use the previous version.

tip

Client closed the websocket connection (safe to ignore)

tip

tip

Nginx does not handle websocket requests. Configure nginx proxy for websockets.

tip

Set larger socket timeout (or 0 to set no timeout).

tip

Upgrade your nanohttpd

tip

It takes too long time for the JVM to find enough entropy for secure connection. Use this jvm option: '-Djava.security.egd=file:/dev/./urandom'.

tip

Upgrade yokozuna
