Hello,

Have you been able to connect with Linphone (or any other client)? With the above config on EC2, Flexisip is running, but not able to connect any user in users.db.txt file with Linphone client.

My users.db.txt file:
version:1

test1@sip.52.x.y.z.xip.io clrtxt:abcxyz ;
test2@sip.52.x.y.z.xip.io clrtxt:abcxyz ;
