Few years ago, i was abble to host a dedicated ark server for me and for my friends to play. They were abble to join and everything went fine until an update (can't remember which one). After i updated my server in server manager, my friends unable to join to my server. I tried eveyrthing, my port forwarding was ok, i used the same when it was worked. Disabled the firewall, download the server manager again, i even reinstalled my pc. and nothing helped. After a few years i tried to play with one of my friends again. I Hosted a non dedicated server, and my friend was unable to join. She get these messages: connection timeout, and unknown error. We even tried with hamachi with the same result. The only way she was able to join is to start a singleplayer game after i started the non dedicated server, and type: open "my hamachi ip"
Now i started to create a dedicated server again using ark server manager. I folowed countles tutorials step by step, but my server only shows up in lan, and my friends can't see it. I literally tried everything to fix this problem, nothing helped. And i'm not the only one. A lot of people have the same issue when hosting a dedicated server, and looks like nobody knows what causing the problem and how to fix it, which is very frustrating.
