Thread:Extension talk:Wikibase Client/Error readapidenied between private clients

I installed a Wikibase repo and 2 clients (all private) but the queries of wikibase between the wikis don't work.

You can see the error when myfrwiki calls a query to myenwiki (event JS in the field page in the popup "Link with page")

I use the parameters for the family wiki and it works : Can you help me ? Thanks
