Lost all access to one of my servers from only my main laptop.

So I added a few more drives to my RAID array on one of my servers and had a large rsync transfer running. I was occasionally checking the progress from my laptop and my phone over the last week (16TB transfer). Had absolutely no issues connecting to my Linux server (Ubuntu Server 18.04) via SSH until the transfer finished and I rebooted the server to be sure all the new mounts in fstab actually held. After the reboot I lost all access to the server from my laptop. I have no access to SSH, Webmin, plex, Samba shares, etc. I can SSH into the server from my phone no problem, I can also SSH into my other Linux server from my laptop and then SSH into the main server from that. I don't have a firewall running on the server, and the only thing I can see blocking access would be fail2ban, but when I check it I see this:

`root@plx-srvr3:/home/sanitized# fail2ban-client status Status |- Number of jail: 1

• Jail list: sshd root@plx-srvr3:/home/sanitized# fail2ban-client status sshd Status for the jail: sshd |- Filter | |- Currently failed: 0 | |- Total failed: 0 | - File list: /var/log/auth.log
• Actions |- Currently banned: 0 |- Total banned: 0
  • Banned IP list:`

I am a bit stumped as to the cause.

Everything is on a single subnet, no VLANs, laptop can access everything else on the network except this server.
