Hello Chewitt,
I am having the same issue with connman resolving to and then failing to reach ipv6 addresses for NTP servers. Switching to ipv4 addresses(e.g.163.172.205.63) in place of domain names (europe.pool.ntp.org) did not solve the problem.
Disabling ipv6 with (echo "net.ipv6.conf.all.disable_ipv6=1" >/storage/.config/sysctl.d/ipv6.conf) stopped the multiple errors from appearing in the journal, but then a (99/Cannot assign requested address) appeared one time. And the date/time is still wrong. Manually setting it (date -s 201902060930) did allow access to Add-on repositories, but obviously auto setting would be best.
I'm at a loss as to what to try next, and would appreciate any suggestions. Some log snippets are attached.
Thank you.
