The opkg update command failed with code 6 - I am stuck

I have been running OpenWRT for years and more or less the same setup, very standard and the only stand out is that I am running a Wireguard client on the router itself. Been zero issues. However, I tried to update the software the otherday and got error "The opkg update command failed with code 6." Went in via SSH and similar issue when running opkg update:
root@OpenWrt:~# opkg update

I guess it's DNS related, but when I try to ping downloads.openwrt.org from SSH and the diagnostic tool within luci it all works fine. I have tried to disable ipv6 interface, add dns to dns forward and some other place I don't remember now but the same issue.

Any pointers?
