TLDR: Almost 10 years of broken multiplayer. Search it yourself.

Multiplayer is still a consistent problem. For me it is non-functional. My 7 year old has to wait for me to troubleshoot Terraria. I'd recommend the game otherwise, and even with the multiplayer issues, i'd still recommend it except for one small issue. If you google "stuck on found server" or "terraria mul" you will see that Google's predictive engine knows you aren't searching for information about how fun it is. Google knows that its broken. The top two suggested ways to complete "terraria mul" are "not working" and "lost connection".

So why is this an issue? Because the results cover the better part of a decade and it its still an issue worth writing articles and guides on gaming media sites about. Google will even help you finish your search by adding what year you want to find broken Terraria help from. Need a Terraria guide from 2020? Perhaps you only want the 2019 fixes. Enough people have searched for their current year that the predictive engine knows you may want a specific year... Google will help you sort through all the results. And what can be found in those results? Helpful forum posts of course, guides, articles, and blog posts.

GUIDES and ARTICLES. Not just helpful forum posts like when you have a driver issue. Games Media actually write blog articles and guides about broken Terraria fixes. Think about that. It's so broken you can make money from advertising by hosting articles about it. And just for clarity: there are articles written in 2020.

Almost 1 decade the developers have been working on this game and you can't just click multiplayer and have it work reliably.
