New install, same problem

I recently installed Zabbix on a new server and migrated over. As it turns out, I am still having this same problem. The host with ip x.10.22.36 has an SNMP Interface configured with this address and an snmptrap.fallback item yet it still does not go to the host. Hopefully, someone can help me. Thanks!
