@redstarfish @prav @cosmin Thanks to @akshay we found out the root cause of SMS not sending - we had configure Prav server to listen only on ipv4 interface so ipv6 requests were going directly to ejabberd (the SMS verification logic is handled by prav server and only prav server can create account in ejabberd after verification). I just confirmed SMS OTP is working on my phone (which was not working earlier). So please try signing up now.
