Exception: Query failed to run by returning code of 504

Dear all,

I’m trying to do a query of my board

query {
  boards(ids: XXXXXX) {
    items {
    id
      name
      column_values {
        text
                    value
      }
    }
  }
} 

and i have this error :

Exception: Query failed to run by returning code of 504.

Do you know what it can be ?

Thanks

Most likely it was network releated issue. The query is ok.
