Hi, My last email was help for admin review. Sharing logs through pastebin https://pastebin.com/6HhdYLJK Interesting part will start from line 983 where it start initializing ndb_mongodb.

sipserver systemd[1]: kamailio.service: main process exited, code=exited, status=1/FAILURE Dec 28 04:44:14 sipserver systemd[1]: Unit kamailio.service entered failed state. As I tried googling the issue and found few issues with tls connection. I set in default kamailio.cfg but still facing the saem issue. enable_tls=no ... loadmodule "ndb_mongodb.so" modparam("ndb_mongodb", "server", "name=cgr91rc8;uri='mongodb://localhost/kamailio'") Its mongodb default installation and its accessible without any auth yet. Please suggest the way farward. -- regards, abdul basit _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org <mailto:sr-users@lists.kamailio.org> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users <https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users> _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org <mailto:sr-users@lists.kamailio.org> https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users <https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users> _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
