FTP issues

Since several weeks I’m experiencing a weird issue with ftp connection. Infuse adds ftp server and recognizes all files on it. But while attempting to add metadata it seems to corrupt ftp connection. First I get the error message that video cannot play. And then ftp server becomes unavailable. Not only for infuse but for another players or ftp managers too. After rebooting my router it can be available again or not. Depends. My ftp server on NAS is OK. It works fine with another media players like AvPlayer or Kodi. I have the problem only with infuse.
Sorry for my English. Any help?
