Hi,
I'm quite new to Proxmox and Datacenter Manager so please bear with me, if I made some rookie mistakes.
I've had five standalone Proxmox VE instances with a couple of VMs and containers running. Now I want to unify my setup. I reinstalled two hosts with a fresh install of PVE and added them to a cluster. Then I installed PDM as a VM inside of this new cluster. I was able to add three of my five hosts as remotes to PDM, the two freshly installed clustered ones and one of the three remaining ones. But the last two give me massive headaches. I can't get them added to PDM as remotes.
If I try, it takes two minutes and then I always get an
I have absolutely no idea, what could drop the packets from PDM to the host...
Oh of course: PDM is version 1.0.2 and one of the offending hosts is 8.4.16, while I upgraded the other from 8.3.3 to 9.1.5. trying to resolve the situation.

If I try, it takes two minutes and then I always get an
api error (status = 400: client error (connect)) message. I poked around a bit and found out that somehow Port 8006 seems to be blocked on those two machines. I never set up any firewall rules inside of PVE itself since I rely on my pfsense box as a firewall. All Proxmox instances are in the same subnet and VLAN (some VMs on those boxes are in different VLANs). I disabled everything in the GUI that could have something to do with the firewall. In the shell pve-firewall status returns disabled/stopped. nmap -p 8006 <ip-address> returns status filtered. I know it's useless but I even created some firewall rules in my pfsense, that specifically allow connections from PDM to the hosts and vice versa. If I remember correctly a nmap filtered response means the packets get dropped and not rejected.I have absolutely no idea, what could drop the packets from PDM to the host...
