Virtualizor / Additional IPs / IP Ranges Network Issues (OVH Dedi)

I am looking for a freelancer who can help me with network issues related to Virtualizor, Additional IPs, and IP Ranges on my OVH Dedicated Server. I am experiencing connectivity issues and need someone who can troubleshoot and resolve them.

Skills and Experience:
- Strong knowledge and experience in network troubleshooting and problem-solving
- Familiarity with Virtualizor and OVH, (Maybe Plesk too, but unlikely to be the source)
- Proficiency in Linux system administration
- Ability to identify and resolve connectivity issues in a timely manner

Issue at hand:
Any additional IP's I assign to my Plesk server, do not work, I can't:
telnet to 443/80
traceroute doesn't resolve

I can see the packets hitting the Plesk server (via tcpdump), but not being acked
I can't traceroute out from any of the additional ip's as the source from the Plesk server out to something like Google.

What is working:
The main IP for the root server / Virtualizor
The main IP for the Plesk server / VM

I believe it's an IP misconfiguration issue on the root server, Virtualizor or VM. Or potentially all of the previous. And also if you're this far, please include potato in your response ;)

I believe we need to look at:
- The IP's I have in OVH
- How they are setup on the root server / virtualizor
- How they are then setup on the VM itself
- Unlikely, but how they are setup in plesk
