Hi Mr. Mohsen,

I added this issue on Github >> https://github.com/ant-media/Ant-Media-Server/issues/1199

I will investigate and inform you.

For a now, if you delete webrtcapp.db in /usr/local/antmedia/webrtcapp.db and restart AMS, this problem will be solved.

Looking forwarding to hearing from you soon.

May the Live Streaming be with you!

Best Regards,
