MUC Users kicked out after restart the server

first of all i had issue to keep users in muc after user go offline but solved this issue from conference settings but now have issue that if i restarted the server all users are kicked from the muc group how i solve this issue ?

Hello,

This is normal behaviour for users to leave the MUC when restarting, but their clients should automatically rejoin when the server is back.

However to note, sometimes this is not the case and users sometimes do not automatically rejoin… I have seen this happen with the dino client.

Can users rejoin manually after restarting?
