IPs not respond on images.ecloud.global

dj0 · July 1, 2024, 8:26am

Hi,

Sorry, but I reopen the topic. But if i can help you.
I don’t know if the right category.

Only one of 4 IPs, 2 IPv4 and 2 IPv6, is available.

IPv4

65.21.238.253 : only one response
135.181.214.98 : Time out

IPv6:

2a01:4f9:6a:4e0d:eeea:2:0:2 : No route to host
2a01:4f9:3a:2c5d:eeea:2:0:2 : no route to host

Browser or curl roundrobin to these addresses

I test on IPv4 and v6 separately, curl wait 3 second and retry 3 times
