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
To IPv4
$ curl --connect-timeout 3 --retry 3 -v -4 https://images.ecloud.global -o /dev/null
