need some configuration help

[sachinbanugariya]

hello.
we are using centos 6, and elgg version 1.7.2
i installed ejabbered using repo, that is running on our server with admin user: http://localhost:5280/admin.

we installed beechat plugin, also added settings and the chat bar is also showing.

Now the issue is when i click on chat bar its loading for sometime and showing connecting.., after sometime its deactivated.
backend error when i click on chat bar is like below:
*106 FastCGI sent in stderr: "PHP message: beechat: get_details" while reading response header from upstream, client: 103.60.176.18, server: localhost, request: "GET /action/beechat/get_details?__elgg_ts=1486567xxxx__elgg_token=45b7a73f6f63d3762dc9d7c71c2xxxxx HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "localhost", referrer: "http://localhost/pg/dashboard/"

so can you please explain how can i resolve this issue.

1. need to know any changes i need to do on beechat plugin after add on elgg mod directory from backend ?
2. on "Chat domain" setting of beechat what i need to fill exactly. need to fill ejabbered server domain name like "http://localhost:5280/http-bind" from frontend ? >>also attached my filled setting screeshot.
3. the issue is seems like not connected with ejabbered.

please let me know how can i debug and where is the issue.
thank you.
