after installing ejabberd_auth_http crash on ejabberd 18.09

[damirci]

I have installed ejabberd_auth_http with this configs:

auth_method: http
auth_opts:
  host: "http://192.168.10.100:81"
  connection_pool_size: 10
  connection_opts: []
  basic_auth: ""
  path_prefix: "/"
auth_use_cache: false
auth_password_format: plain

and I coppied beam files from C:\ProgramData\ejabberd\.ejabberd-modules\ejabberd_auth_http\ebin to C:\Program Files\ejabberd\lib\ejabberd-18.09\ebin.

when I want to authenticate to admin panel this logs generates is log files:

exception error: {{badmatch,{error,econnrefused}},[{ejabberd_auth_http,make_req,5,

This line says that, when making a HTTP request, ejabberd got the connection refused.

In case you need help debugging the problem: If you set loglevel to 5 in ejabberd.yml, you should get a log line indicating the Path that is to be requested, just before the crash.

just logs in ejabberd.log changed like this:

I get that same error message when I attempt to connect to an IP address and port where nothing is listening. However, if I set the IP and port of an accessible web server, then the connection is established, even if that server has nothing to do with me.

For example, configure the module to use www.google.com (which obviously will fail the auth, but at least accepts the connection):

auth_opts:
  host: "http://216.58.211.228:80"

16:16:18.708 [info] (<0.505.0>) Accepted connection ::ffff:127.0.0.1:44605 -> ::ffff:127.0.0.1:5222

It maybe late but FYI, in the latest version, there is ~/.ejabberd_modules/ejabberd_auth_http/conf/ejabberd_auth_http.yml file which will somehow override the configuration for _ejabberd_authhttp in your ejabberd.yml, you can modify ejabberd_auth_http.ymland don't need to copy _ejabberd_authhttp.beam into your ejabberd ebin installation dir.
