I can't understand the totorial
I didn't make an explicit tutorial, and I have to admit, I didn't use the tutorial much either, just barely enough to be able to make the VM in the first place.

Here's what I had to do to get the first VM running though:

I set up the tiniest vm I could on google cloud. an e2 micro, and set the computer type to Ubuntu 18.0 something
then in the VPC Network>external IP address, made the IP address for the vm static
then in the firewall made a new rule for incoming traffic in ip range 0.0.0.0/0 port 9999 to allow the games to connect.
then I ssh back into the vm (there's a button for it in the vm overview)
then I set up a tiny github repository so i can load some files on it https://github.com/Vendily/cable-club-v18
in the ssh terminal, I used git clone https://github.com/Vendily/cable-club-v18.git (but you'd have to use your own if you have custom pbs files).
cd into the newly created folder, then python3 cable_club.py --host [your external IP] (mind that this doesn't keep it open when you close the terminal, just for testing)
the real deal is nohup python3 cable_club.py --host [your external IP] & then it runs in the background.

Vendily updated [v16/v17/v18] Cable Club with a new update entry:

Bug fixes, QoL, and Mail, oh my!

Here's a big ol update to make version 1.4!
No, there's still no v19 support.

In this version, I fixed the :switch and :choice symbol being sent when not expected. The former was because the pokemon selection in the command phase also used switch in between, so it sends an unexpected symbol if you just open it at all. The latter is because the regular end of round switch would proc in a different order for both sides.
I also fixed an issue with the server script, in that the --host and...

Vendily updated [v16/v17/v18] Cable Club with a new update entry:

Trade confirmation and Improved Variables sent

View attachment 4439
So we have the an improvement to the trade, a confirmation screen that lets you view the summary of the mon traded and let you double check before trading, instead of sight unseen like before.

With this, we also send more variables, and also stop sending stuff that isn't necessary, like we don't need to send gender if it can be calculated from the PID or overridden by the gender flag.
This did require adding a new constant to the server, for if it's v18, as...

I'm wondering if you could add a Mystery Gift like online component considering MG is broken in v18

Would anybody be willing to help through the steps of setting this up in my game? I'd pay you for your time or even message me about it. I am not knowledgeable when it comes to servers and python.

Vendily updated [v16/v17/v18] Cable Club with a new update entry:

V19.1 Support! Cross Platform Cable Clubbing!

Yep, you read that correctly, we got v19.1 support, and MKXP too! That means you can connect to the server from Linux (and probably Mac OS) too!

One catch, you need to update to MKXP-Z 2.2.3, since it takes advantage of a larger standard library to require 'sockets'

Oh, and also the game segfaults in debug mode when the shell is open. Don't know why. It doesn't happen if you launch it normally. Don't...

Vendily updated [v16/v17/v18/v19] Cable Club with a new update entry:

Online Trainer Types and Out of Game Server Config

Both versions of the script get an update here. v19.1 goes to 2.1, while v16-18 goes to 1.6, because we got some changes!

First on the list, Online Trainer Types. Since the Union Room used to assign trainer types for an overworld, this is basically that. You can call pbChangeOnlineTrainerType to have a premade method that works with the ONLINE_TRAINER_TYPE_LIST array. It uses the text that the Psychic in DPPt had.

ONLINE_TRAINER_TYPE_LIST is an array of arrays...

Is there a way to set this up via an InfinityFree server? I see that a Ubuntu VM is usable, but what about in InfinityFree?

Well, I fully set it up exactly like in the tutorial, and I cannot connect to anyone. So this is currently broken for PE v19.1...

@Vendily I'm still having issues with the script. I'm getting the following error:

I never get a successful connection in any case, and I've tested more than a dozen times.
Just checking, you don't have a serverinfo.ini file overwriting the IP address it's checking, and you also compiled your plugins after changing the HOST?

No, I never set up a serverinfo.ini file, as I'm the only person hosting a server. And yes, I always compile everything after every change. I have no idea if my tester has compiled plugins, but that should produce a different error, right? I get no activity from the VM's SSH shell when trying to connect as well.
