Redfire Desktop Screen Publisher/Viewer issue

Hi All,

Currently I’m using

Openfire 3.7.1

Spark 2.6.3

I have installed redfire-370-0.0.06. I’m able to publish my desktop screen thru http://your_openfire-server:7070/redfire and my colleague can view it from URL too (Please refer to my attachment URL.png) but both of us unable to publisher/viewer thru spark messenger icon (Please refer to my attachment Spark.png). Even we try to click on the start sharing button it look like no any response. (Please refer to my attachment Spark II.png)

We need to configure any setting?

Need some advise. Thanks

Best Regards,
