Find address candidates by magic key doesn't work

[GISADMIN911]

I have a composed locator built with ArcMap 10.5 and published in Server 10.5.1

For dual range locators (inside of composed) the search for candidates by the magic key (without the singleline) does not work for me on the 10.5.1 server.

What can i review?

Do you have the ability to migrate to Pro locators at this time?

[GISADMIN911]

YES. In fact, I have it created in Pro 2.8 but I get the same result on server 10.5.1 (here I have no option to change version)
