Https web monitoring

[Ferke]

Hi,

I would like to check a webpage in zabbix, but I have faced a problem.
I have a host which reports data to 3 servers, but the https web scenario check is working only on one server.
All of them is Ubuntu.
First one: Ubuntu 16.04.2 LTS and Zabbix 3.2.4 (it is working)
Second one: Ubuntu 16.04.2 LTS and Zabbix 3.2.4 (it is NOT working) (docker based)
Third one: Ubuntu 14.04.5 LTS and Zabbix 3.2.6 (it is NOT working)

The first (working) server was the first in the zabbix_agent.conf, I tried to reorder the IP addresses and disable the host in the "good" zabbix server, but the result is the same.

What can be the different on the servers? Why the http works fine but the https not?

Hi,

There is a https webpage what I want to check from a certain host.
I added a web monitoring item for the same host in all three servers, so the host and the configuration for the web check is the same on all servers.

As I mentioned in case of one server it works fine.
And where it doesn't work I get this error message:

Step "Authentication check" [1 of 1] failed: Timeout was reached: Connection timed out after 15001 milliseconds

I tried a non https (http) web check from the problematic servers, and it works fine. And I tried a few https webpage (for example google.com), and the result is the same: only 1 of 3 servers can handle it.

Do you have any idea?

Thanks in advance!
