    All web scenarios alerting - Couldn't resolve host name: Unknown error

    I have around 200 web scenarios with 1 step for each one, it was all working fine but in the last few days suddenly all of them start alerting as failed with this next error but if i check them manually all respond just fine

    Step "XXXX" [1 of 1] failed: Couldn't resolve host name: Could not resolve host: XXX; Unknown error

    I dont see any alerts or details in the zabbix dashboard that could indicate performance issues (Like http pollers busy or else)

    Any ideas of what could be causing this?

    Actual config:

    StartHTTPPollers=30

    Could not resolve host ...
    Something with the name resolution in your server?
