HP SMART no longer finds HP Envy 4520

[Mad44]

Have used HP Smart on my Android phone for years to print on my HP Envy 4520. Worked fine.
Now the HP Smart cannot find the printer. Both on same network. My Surface with Windows 10 can use the app and print to the Envy. My IPad with the HP Smart app can find the Envy and print. The Android stopped finding the Envy and nothing changed. Virtual Agent is of no help. When I tried printing from the app directing using WiFi I was informed my password was incorrect. The password is working on all my other devices. Been trying for hours to solve

Welcome to the HP Support Community.

Uninstall and reinstall the HP Smart App on your Android phone and try.

If that doesn't work, reset the network settings on your phone and connect it to the Printer again.

Let me know if this helps.
