Something not 100% with ipv6 after changes made from long to short notation

Changed ipv6 to short notation but not working with the GUI of virtualmin assigned servers.

I changed the server ipv6 base host from:.

xxxx:xxxx:xxxx:1865:0000:0000:0000:0001 to


After that al seems to work for months, also did under > virtual server configuration > change ip

New IPv6 address > Shared address > shared server to xxxx:xxxx:xxxx:1865::1


Dashboard > IP Address Allocation :
xxxx:xxxx:xxxx:1865:0000:0000:0000:0001 (Dedicated IP) 7 virtual servers.

Wen i klick on the 7 virtual servers comes
No virtual servers containing xxxx:xxxx:xxxx:1865:0000:0000:0000:0001 were found.
