Network connection error

I have always Network connection error when I try to explore my folder on NAS, only occurs with my MAC (latest version App) but with IPAD works.
I don´t understand nothing with my MAC I see all folders on NAS and I play all songs with foobar or Elmedia player. If explore manually in RA250 with touchscreen works fine. All works fine Tidal since MAC with Rose connection.

Any suggest

Thanks and regards
