Yes, I have reproduced with emacs -Q

I could follow it first time. Now when I review again I cannot follow
it. I have opened xterm inside and I could follow it. Now I opened
xterm and I cannot follow it.

I have noticed that "Y" causes wrong relative symlink, this one here:
S lrwxrwxrwx 1   65 13. Jun 14:51 2020-06-13 -> 
../../../../../../public_html/louis.club/media/2020/06/2020-06-13

And it should be this one:
S lrwxrwxrwx 1   71 13. Jun 14:51 2020-06-13 -> 
../../../../../../../../public_html/louis.club/media/2020/06/2020-06-13

And I have made that symlink from:

/home/data1/protected/public_html/louis.club/media/2020/06/2020-06-13

to

/home/data1/protected/Media/Pictures/Pictures/Year-2020/06/2020-06-13/2020-06-13
as symlink to 
/home/data1/protected/public_html/louis.club/media/2020/06/2020-06-13

I guess if you would recreate same directories at your side, you could
reproduce it.

The "Y" I used belongs to dired-x library.

In my opinion the error is in the calculation for relative
symlink.
