Preserving my first Minecraft game on Ubuntu 22.04.1 from earlier Ubuntu server

My first Minecraft game was 1.8.8 on my local Windows machine. I built a stand-alone Ubuntu Server 16.04 (actually probably started as 14.04 but upgraded along the way) and did a build of Spigot 1.8.8 and put the world there. The game is running fine on that original server, but I feel its time for an upgrade, so I've built another stand-alone with Ubuntu Server 22.04.1, adding nothing in the installation except for SSH, and Samba after.

I followed DigitalOcean's instructions to install the Minecraft on the new server, giving me a working 1.18.2 game.

Next, I used scp to copy my 1.8.8 game folder to the new server. In the ssh terminal the game loads properly, either with the spigot .jar or with a mojang, and I get the "Done" message, but when I try to join from my Windows Minecraft client, I get 'java.io.ioexception...' and the text in the ssh terminal turns into a blur. The standard CTL+C, X, Q don't stop the blur of text, and the only thing I've found I can do is close out ssh and reopen a new session.

I've tried:

A new build of the latest from SpigotMC, first without installing java on the new server since I used DigitalOcean's instructions to do that already, then going back and installing SpigotMC's sudo apt-get install openjdk-8-jre-headless except for git they recommended because I already had that.
Disabling all the plugins I'd added at some point
The aforementioned trying both spigot_1.8.8.jar vs. mojang's
Adjusting the arguments for both the server start.sh and the client's to both more and less memory.
Changing ports and and online-mode in server.properties
Adding firewall rules
Reboots of both client and server.

I haven't tried:

Changing DNS as suggested in posts dating back to 2016-7, because without even restarting the server after the crash, I can go back in a new ssh session and successfully get Minecraft 1.8.8 to completely load. Also, without restarting I can get the DigitalOcean installed Minecraft working fully, with no error when joining.
Resetting the router for the same reasons as #1

Has anybody run into this problem and come up with a solution?

Thanks.

Does Minecraft have its own support site?

@David, they do, but this issue seems closer to an Ubuntu-java interaction issue, probably from something I've done wrong. The game itself shows itself to be loaded on the server successfully but on connection attempts I get the error. Also, I'd started using 3rd party built .jar files.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
