I was playing game and it crashed on 12/3. When I tried to log back on I get message that server is closed and cant be selected. I get this on all North American servers except South America. As of 12/4, game is still not accessible. I have submitted a web ticket as well to support.
Hi @rick.knisely4.
Welcome to the Lost Ark Forums, hope you’re great 
I’m sorry that you’re getting this “regionunavaliable” error that prevents you to play Lost Ark, I understand how frustrating it would be, also thank you for providing all the information so far.
When you have a chance if you didn’t do so, please Follow these troubleshooting steps in order to help you:
-
Try adding Windows firewall exceptions manually:
Press Windows + R, type “firewall.cpl” into the Run window, and then press Enter.
Click Allow an app or feature through Windows Firewall and then click Change settings.
Look for the game in the list of allowed apps and features. If it’s present, make sure it’s checked, and that both the Private and Public columns have a check mark. If the game is missing from the list, you must add it.
Click Allow another app…, locate and select LostArkLauncher.exe, and then click Add.
Once you’ve done that, make sure that Lost Ark has check marks under both the Private and Public columns.
Also thank you for let us know you made a ticket with customer support, if this issue persist please make sure you send this link to the agent so we can help you to investigate this issue, also give them all the information needed. And please let me know how was it!
Stay Safe 
I’m also having this issue but im on NAE. I tried the troubleshooting steps you recommended and it did not work, is there any other troubleshooting options or am i out of luck?
I am having the same issue on NAE and none of these worked for me either.
I’m on NAE and my husband and I are both having the same exact problem. I’ve done every single fix that I’ve seen regarding this and nothing is working. It is frustrating.
Same for me
This isn’t the issue. My firewall is already allowing Lost Ark for everything.
The other post has shown it connected to the ISP itself.
Why are we being blocked all of a sudden?

Hi @defeoboutique.
Thank you for your input, however each case is different, as mentioned before; I will update this post as soon as I get more information, we cannot ask sensitive data due security reasons.
We hope you understand.
Is it more of a blanket ISP problem? Everyone else on the other thread seem to have the same ISP, including myself. Updates are greatly appreciated.

So everyone that uses Suddenlink/Optimum all have a unique separate problem?
I’m sorry but this has been going on for over 24 hours.

Try using warp 1.1.1.1
And
Find EFGame/Config/UserOption.xml
Make a backup of that file. Delete (the game will auto create the file on load if you delete it) or edit that file, in the end of the file you can specify a region like NA for example

I also did this already, no response yet.
Getting same issue on NAE. I sent my report over with a video of my error through a ticket but I hope we are compensated for this downtime
This issue appears to be relate to the ISP carrier. I have 2 homes and my issue occurred in Arizona with the carrier SuddenLink/Optimum. I have now moved to my home in California which is AT&T ISP and I was able to access the game with no issues.
Still having this issue a whole 24 hours later, Amazon please fix this its a issue on your side.
