Unable to create websockets listener on port 1884

[abhion]

I did a detailed log and got this

1576674012: mosquitto version 1.6.8 starting
1576674012: Config loaded from mosquitto.conf.

The error 10048 given here indicates that the port 1884 is already in use. Do you have something else running that is using that port?

This probably started happening after I enabled ssl mode as instructed here: http://www.steves-internet-guide.com/mosquitto-tls/. I saw that mosquitto.exe was using the port 1884. I restarted mosquitto service and I ran the config again. Now I get

1576718626: mosquitto version 1.6.8 starting 1576718626: Config loaded from mosquitto.conf. 1576718626: Opening websockets listen socket on port 1884. 1576718626: libuv support not compiled in 1576718626: Creating Vhost 'default' port 1884, 3 protocols, IPv6 off 1576718626: Using non-SSL mode 1576718626: Opening ipv6 listen socket on port 1883. 1576718626: Error: Only one usage of each socket address (protocol/network address/port) is normally permitted.

This is how I enabled websockets in the config:

#protocol mqtt port 1883 listener 1884 protocol websockets

@ralight i got it to work by stopping mosquitto in Services.

But in the log i get 1576718626: Using non-SSL mode though i added the path for the keys and certificate.

`# "openssl rehash " each time you add/remove a certificate.

cafile C:\Users\DemoEngineer\Desktop\cert\ca.crt

capath

Path to the PEM encoded server certificate.

certfile C:\Users\DemoEngineer\Desktop\cert\server.crt

Path to the PEM encoded keyfile.

keyfile C:\Users\DemoEngineer\Desktop\cert\server.key`.

Why can't I enable SSL mode?

If you've copied those lines as they are, then the cafile, certfile, and keyfile lines are all commented out. Please try removing the # at the beginning of the line.
