[Freeswitch-users] Websocket closed unexpectly

Hello I am working on FreeSWITCH 1.10.6 ans sip.js 0.16, and very often, I have a deconnection of the WSS session. The error message on javascript console on Chrome is "error 1006 - websocket unexpectly closed" This issue is very random but very often, and it breaks the incoming call. Do you experiment such issue ? Do you know how to solve it ? thanks Franck
