Version 1.6.2 websockets error in Windows: "Error in poll: No such file or directory. "

[gcser]

Hi!

I downloaded and installed the 1.6.2 x64 version (binaries). After enabling the websockets, the log file fills up with the error message: "Error in poll: No such file or directory. ". In a few seconds a thousands of error messages logged.
If I comment out the websockets support, this error does not happens.
What could be wrong?

I'm not sure, and I can't get access to a Windows machine to test it for about a week I'm afraid.

+1 - same here!

After testing around quite alot, I think I've figured a configuration that works:

port 1883
protocol mqtt
socket_domain ipv4

listener 9001
protocol websockets
socket_domain ipv4

If I remove the protocol mqtt part, it breaks again. So for some reason there needs to be both. I'm not 100% sure if the socket_domain part really is necessary, but for my usecase it surfices.

corelgott: thanks for the solution, I've tested it, and it works! :)

Same works for me by adding socket_domain ipv4.
Just for future reference, I had a working eclipse-mosquitto docker image in my ubuntu server 18.04 LTS until I removed ipv6, so seems like the docker can't listen to ipv6 sockets and just fails.
