Zabbix 7 SNMP no response after rebooting network switch

[ZabbMice]

Hi All,

I have successfully discovered a network Switch (Aruba) in my Zabbix 7. However, the snmp polling stopped once the switch got rebooted. There is no other dependency, since I can discover new switches in the same subnet using SNMP.
I am new to the Zabbix world.
Please guide me to find the root cause.

Thanks.

I have seen the same issue was there for lot of people. But I couldn't find the solution for this issue. Anyone can direct me to the solution please?
