Zabbix Proxy to Zabbix Server Connection is intermittent

[satheshr90]

It looks like connectivity between Zabbix Server in cloud and zabbix proxy is not stable and is intermittent with following set of errors:
In Proxy Server:

From n/w side, MTU is set at 1500. But still n/w team is looking for some options to see what is missing. But still wanted to know, what else could be the issue here? Please help.

Hey all,

We are experiencing an issue in our Zabbix environment where the zabbix agent reports as being unreachable, but we can still ping the host and the service is running.

We are currently using agent.ping for the item and our trigger is {host.name:agent.ping.nodata(5m)}=1

Our graph shows the below.
