I’ve been traveling and working online for the past year and a half now and I’ve made money in a lot of different ways! Some I liked, most I didn’t. Here’s a brief rundown:

Data Entry - I have done several different data entry jobs which paid really well but were mind-numbingly boring. Just staring at the computer all day, copying numbers and information from a document into a spreadsheet. Usually these jobs only last a day or two, so that’s an upside.
You can find data entry jobs on websites like Upwork or Flexjobs - and you can do them if you have basic reading, typing and Excel knowledge.
Freelance Social Media Management - This is something I actually still do. I learned a ton about Social Media Marketing and how to gain followers and get leads from Social Media - so I started freelancing for entrepreneurs and small businesses managing their accounts. It didn’t take long for me to learn Social Media Marketing and this has been my primary source of income.
There are lots of opportunities for this kind of work on Upwork(.)com and Flexjobs(.)com - and you can learn pretty much anything you need to know on this subject on Udemy(.)com.
Selling Digital Products - I have created and sold my own information products including ebooks and a mini-course on Instagram Marketing. I wasn’t enjoying this as much and actually working a lot more than when I was freelancing, so I didn’t do this for very long.
Drop Shipping - The first thing I tried to make money online with was drop shipping. If you don’t know what drop shipping is, it’s basically selling physical products online from a website like aliexpress(.)com or even Amazon. You don’t keep any product, and you don’t have to worry about shipping. You have to set up and maintain an online store, and send the orders through to the manufacturer.
I had a bit of success with this, but ultimately I quit doing it because I didn’t feel great about selling physical products. As a nomad, I’m a minimalist and it felt slimy to me.
I have also worked for a free place to stay, which wasn’t making money but it sure saved me a lot of money!

I’ve done more than what’s on this list, but this is the majority of what I’ve done since I’ve been traveling. It always takes a while to figure out what you like and don’t like - and the only way you’ll find out is to just do it!
