[SOLVED] Email Notifications Stopped working

[Jarvar]

Hello,
So I have a couple of test systems in my home lab.
Created a cluster and joined a node to it. Couldn't really achieve what I wanted so I removed the nodes and cluster.
However, on the node I removed. I reinstalled the proxmox and setup a storage ZFS pool the same as before. Things seems okay, but when I run a crontab job where a smartctl runs on the drive and I am supposed to receive an email it does not work.

when I run

echo "test from cluster" | mail -s "test"email@example.com

I get connection timed out and network unreachable and no delivered mail.

Any assistance would be much appreciated.
Thank you.
This is the same for the node which I created the cluster on and also the node which I reinstalled and it doesn't work.

Funny thing, I put this server on different network at a different location and email notifcations are working.
It was all working before, I think I only started losing email notifications after I created a cluster.
I have since deleted the removed the cluster and nodes and reinstalled PVE 6.1

One thing that is concerning with a node that was joined to a cluster was that there was some Eror INIT Error with a drive and code 303 maybe.
I am trying to find it again. But I deleted the node from the cluster and reinstalled PVE on the drives.
However I did run it up again on the same network that I had the cluster. I did remove the cluster according to this tuorial though.

Any thoughts?

Noticed some logs with the IP address of the PVE installed server on the router. I tried rebooting the router, lo and behold it works. Sorry for the inconvenience.
