Zabbix Agent errors, new v5 server

[moxy]

In the past when I moved my Zabbix server all my hosts would reregister and things would go about as it previously did. This time using v5 things didn't quite go as planned and a bunch of my agents are reporting errors.


There are a bunch of other people in the forum who had the same problem but they fixed it by manually readding the host using the same name but I had an autoregistration rule previously that didn't run into the issue.

Also, previously there were options in the Zabbix_server.conf where I could put in an FQDN for my server but it appears to only accept IPs now.

Looks like I'm going to need to make changes but I'm not sure what I need to do. Any help/suggestions/prods into the right directions is appreciated.

"previously there were options in the Zabbix_server.conf where I could put in an FQDN for my server"
What parameter that would be? Cannot find such thing in any of old server conf parameters... (searching for "name").

If your autoreg rules dont work any more.. anything in server log? Is it failing always or just for some hosts? Can you upgrade agents also to v5 ?

I might have that mixed up with the agent.

Is this an issue with the template?
