Is the ChuChu Rocket server currently under maintenance?

[Suzaku_Hanamine]

Hello everyone.

Yesterday, the setup of DreamPi was completed and I was able to browse the Internet with Dreamcast.

When I tried to play online, one problem occurred. That is, I can't play a network of ChuChu Rocket.

Specifically, although it can be connected to the Internet, it is displayed during server maintenance and can not enter the server.

However, I realized that I had forgotten to set the DMZ, so I opened the port and set the DMZ while looking at the router manual and the Internet tutorial.

Nevertheless, it cannot be connected to the online server.

I think the following reasons are:

1.My ISP(In my case, I use ITSCOM) may be blocking use of third-party DNS servers
2.I Failured DMZ and port forwarding settings
3.As shown, the server is under maintenance

1 has not been confirmed yet. (Because my parents have contracted ISP)

Regarding 2, the possibility is the highest because I am a beginner in DMZ and port settings.

The problem is the third. I do not know the information that the chewche rocket server is under maintenance. I want to know if such information is true, or a lie, or if the CHUCHU ROCKET server is now accessible.

Finally, I will present my circumstance:

Country:Japan
Dreamcast's region:NTSC-J
ISP:itscom
