(Service Check Timed Out) in RAW edition 1.6.0p11 (centOS 8)

My SNMP check interval is 5 minutes and timeout is 120s.
It’s very strange because I have problems on all switches, (smallers like HP-1810-8G and larger switches like HPE Office Connect 1950 12 XGT 4SFP+ or stacks HPE Office Connect 1950 48 ports)

I’ll try to increase check interval…
