FTP error: can not send file to printer

When sending work to printer over WLAN, it loads until 70% and the stops. After while comes error message

  • Error Code:-4020
  • Error description: Failed to send file via FTP…
  • Extra info: [ftp code]:28
  • [Reason]: Timeout was reached: FTP response timeout

Versions:
Bambu studio 2.0.3.54
BL X1-Carbon FW 01.08.02.00

ping gets reply from printer

Looked that other thread and I always import only STL, no projects

But If I’m using other computer with BS version 1.9.5.51 I can send files without any problems. Same printer, same WLAN
