I'm currently trying to installed Zabbix on Unbuntu server, but I continue to get this error message:

Connecting to repo.zabbix.com (repo.zabbix.com)|87.110.183.174|:80... failed: Connection refused

this is what I type in to get to zabbix download:

wget http://repo.zabbix.com/zabbix/2.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_2.4-1+trusty_all.deb

please help me with issue?
