Medium severity Installation Code: Something Went Wrong HP

HP Smart app: "Something went wrong" during setup

The HP Smart app shows a generic "Something went wrong" while adding or setting up a printer. It's usually a connection, band, or app-cache issue rather than a printer fault.

Symptoms

  • "Something went wrong, try again"
  • Setup fails partway
  • Printer half-added

Likely causes

  • Phone/PC on 5GHz while the printer needs 2.4GHz
  • Printer not in setup mode
  • HP Smart cache/outdated app
  • VPN or firewall interfering

How to fix it — step by step

Work through these in order; most people are fixed by the first two or three.

Use 2.4GHz and setup mode

Connect your device to the 2.4GHz network and restore the printer's Wi-Fi setup mode (Wi-Fi Setup Wizard or restore network defaults).

Update or reinstall HP Smart

Update HP Smart to the latest version, or remove and reinstall it to clear a corrupt cache.

Disable VPN / allow through firewall

Turn off any VPN and allow HP Smart through your firewall during setup.

Restart everything

Restart the printer, router and your device, then run setup again with them close together.
