Since the most recent patch most servers from most providers are having stability issues with Ark. I think there are so many tickets being made currently regarding these issues they are overloaded. Give them some time and I am sure they will get to you asap.
Regarding the server browser thing, from what I read from this provider and other providers this is pretty much out of their control, the first server I had was in the unofficial browser within 30 mins, my 2nd server took longer, I needed to add my server via steam directly and then after a day or 2 it popped up in the unofficial listings.
I hope your server is working as expected soon
FYI, I just restored a backup of my 2 main ini files from this morning with the changes I needed manually, It is working now. but you need to fix the tool
Thanks!
I just used the "Modify Game Settings" and pressed save, now my game.ini is full of changes that I did not change. It would appear the values in the modify tool are messed up completly. please take a look. Server: 11136
