Return of Reckoning

I checked because I have a local cable modem from another company at home. The cable modem connects to the server normally. However, the only thing that is not connected to the server is the SKB provider line and I replaced it with another company.

Do you use the SKB line? I was using the Internet provider and couldn't connect, so I filed a complaint and replaced the line with another company, and it worked properly. It was an Internet provider's problem.

I've been playing ROR for more than a year.
I would like to ask if you have set up an inaccessible IP among the server operation policies. I received an answer from the Internet provider that there is no problem. Please check.

It has been identified as a problem with the internet line provider I use.

After executing the launcher, the server access window appears.
And after pressing the select button, I can't access it with the sign login timed out.
I'm playing in Korea, and until yesterday evening, I accessed the game normally and played.
I'd like to ask you why I can't access it. Thank you.

I played normal until yesterday.
But now I can't connect to Timed out in the server access window after running the client.
Can anyone explain this situation?
