Proxmox: API service not available - Unknown Error (520)

[Maxi]

Hello,

As the title suggest, I am experiencing an issue with the template "Proxmox VE by HTTP"
To setup I have followed this guide:

https://www.zabbix.com/integrations/proxmox

I have also verified my setup according to this video:

https://www.youtube.com/watch?v=qtw4PQR7kDA&t

I have installed Zabbix agent 2 on multiple nodes across multiple datacenters and it works well.
When trying to create another host with Proxmox VE by HTTP to monitor the clusters I get problem 'Proxmox: API service not available'
When checking last value, I am getting 'Unknown Error (520)'

The same issue occurs on any node, any cluster.
These are different setups, with different Proxmox versions installed but all yield the same result.

I have checked the connection from Zabbix server to Proxmox with the same host, PVE.TOKEN.SECRET and PVE.TOKEN.ID using CURL and it is authenticated successfully.
At the moment I am lost and don't know how to continue debugging. Any kind of help would be greatly appreciated.

Thank you!

I've had the same issue. Found it in this topic: https://www.zabbix.com/forum/zabbix-...te-not-working
My zabbix is on redhat and I had to run this command: setsebool -P zabbix_can_network 1

Also you dont need the {$PVE.URL.HOST} if you add the proxmox servers as agents.

Still relevant - any insights?

hey, how are your macros configured?
Did You setup the API token properly in proxmox?
