we have a REM with Nginx reverse proxy deployed in lab.
we found IE browser can setup rem call with finesse agent, but, after 1,2 mins, IE browser plugin will reconnect the call again automatically,
but, preivous call is still active, which means IE browser plugin will call the pilot number again.
so, from IE browser, we can hear serverl agent talk to customer.
but, if we bypass nginx, which means IE browser calls to reas directly, we did not see this issue.
we attached IE console log for your reference.
please let us know whether it is known isssue and how to resovle it.
As you realised off forum the issue was down to a mis-match between the Nginx proxy_read_timeout (defaults to 60s) and FCSDK Webrtc Client Ping Poll Period (keep alive) on the web_plugin_framework/webcontroller/admin/ page which defaults to 150 seconds.
We recommend reducing the client ping poll period configuration in REAS down to 30 (seconds), found on https://REAS_SERVER:8443/web_plugin_framework/webcontroller/admin/ page.
In REM 11.5 the default Client Ping Poll Period will be 30 seconds.
