Site hardly loading / timing-out when using IPv6
-
I have recently noticed that jnovel loads very badly sometimes to the point of timing-out. Thanks to another user on discord (in
#report-issues) also having a similar problem and then noting that disabling ipv6 for them fixed the issue. Then once it happened to me again (today), i tried forcing j-novel.club to be ipv4 and the problem instantly went away.It might also be possible that my previous post was affected by this https://forums.j-novel.club/topic/7692/slow-book-downloads?_=1716305606019
For reference, the ipv6 that was badly loading was
2a06:98c1:3121::b:.
DNS provider2001:4860:4860:0:0:0:0:8888(google ipv6) &2606:4700:4700::1111(cloudflare ipv6).Locating: Europe / Germany

Now some hours later, i see that it actually still happens, even with forced IPv4.
EDIT: i had just tried re-enabling IPv6, but that made it even worse.
So my conclusion currently is:- IPv6 is definitely broken, with a connection of at max 7kb/s to timeouts
- IPv4 has a stable connection of 10kb/s to 100kb/s without timeouts
This happens randomly at times and i dont know why (is it high traffic times?)

After creating this issue, i basically forgot about it with the fix of disabling ipv6 for j-novel.club.
Recently i removed the block on ipv6 and did not have this problem anymore, consider it having been a intermittent problem which is now fixed.
