So I've been searching around for a few days for any reason for why my Rust server browser will not display to me more than 100 or so servers MAXIMUM. Before I came back to Rust there were only about 100 or so servers up, so this wouldn't seem to weird to me, but when I log in on my other computer *On my college campuses wifi* i see upward of 1500 servers between officials, modded, etc.
If this isn't weird enough, whenever i try to connect to any of the 5 or so servers that have more than 0 players out of the 100 i can see on my primary computer, it will load for a brief amount of time then send me back to the browser with the message saying "Error trying to connect". or something along those lines.
My internet provider isn't very good, (It's my local, expensive provider) the internet is fast when it works, but the vast majority of the time it will be connected but unable to load internet browsers, or load them extremely slow.
Yada yada internet problems, It may be useful information to someone who would be helpful enough to assist me
I had that problem about two weeks ago. All I did was uninstall and clean steam and reinstall rust and problem solved. I'm not saying that is the case for you, just what happened to work in my situation.
