The server Valkyr RO seems to be dead. Their Server Info page on RMS (https://ratemyserver.net/index.php?page=detailedlistserver&serid=20934&itv=6&url_sname=Valkyr%20RO) has the following links which lead to a dead end (https://i.imgur.com/Lv6VTIr.png). And, at the time of this post, there haven't been any reviews for the server for almost 140 days.

Edit:
Valiant RO's (https://ratemyserver.net/index.php?page=detailedlistserver&serid=20930&itv=6&url_sname=ValiantRO) site (https://i.imgur.com/4N9sfl3.png) is down too, as well as its control panel (http://valiant-ro.com/cp).

Edit 2:
Got curious and kept clicking on servers. Asgard Legend (https://ratemyserver.net/index.php?page=detailedlistserver&serid=20502&itv=6&url_sname=Ragnarok%20Asgard%20Legend) has no reviews for a while, and a site claiming to be under construction (https://i.imgur.com/2ChWrVj.png), leading me to think it's dead.

https://www.asgardlegend.com/main/play (https://www.asgardlegend.com/main/play)
The first two has been delisted, thanks for letting us know.
Asgard legend I believe they are still alive.
Asgard Legend is still alive and their Discord Community is always on.
Don't think their website is "under construction" no more. But, anyways, they are a little bit late in content, but... there's so much new take on old content and poetic licence (like Dynamic Weather), that it takes a bunch for u to miss smth. Also, the class balance is ridiculous. Theoretically, every class is rly good. /lv
