All links from the domain (placeholder).jype.com keep being seen as dead by the bot, while they are alive (false positive).

The error given is (NO RESPONSE FROM SERVER) while in fact the pages load within a reasonable amount of time.

Example which I reported as false positive today: https://twice.jype.com/notice.asp?idx=1432&page=21&vnum=157

Example which I have reported as a false positive before: https://twice.jype.com/notice.asp?idx=1891&page=&vnum=377
However this link was again considered dead by the bot, and using the false positive report function: "These URLs are already reported and will be ignored" is given. I have manually put this link on alive again.
Unfortunately this happens every time with all of the links from this domain that have been reported as a false positive before.

As a note the links I provided are https://twice.jype.com, but https://jyp.jype.com/ https://2pm.jype.com/ https://got7.jype.com/ https://day6.jype.com/ https://straykids.jype.com/ https://itzy.jype.com/ https://yubin.jype.com/ https://wondergirls.jype.com/ https://jjproject.jype.com/ https://nakjoon.jype.com/ https://jus2.jype.com/ with their associated pages (same links like the twice example above) also exist, as does https://www.jype.com/ and its associated sub-pages. Update: I saw some of these and they ecounterd the same problems
