Square Point of Sale Freezing/Connection Error after Update

found-gaming — Sat, 20 Sep 2025 11:16:54 GMT

After the most recent update to Version 5.79, we've been having intermittent freezing issues with Square Point of Sale on our Ipad/Square Stand. Today, it won't load. The app starts, beeps to confirm that hardware is connected, stays on the Loading screen for a couple of minutes, and then gives one of the two following errors:

Connection error. Unable to connect to the Internet. Please check your network connection and try again.

Connection error. Unable to connect to the Internet. Please check your network connection and try again. Error code: FD4

It won't do anything else, just loads and alternates between the two errors.

Tried updating, uninstalling, reinstalling, restarting, restarting our router, having our ISP reset our gateway, switching from Wifi to 4G (different carrier), and turning airplane mode on and off; everything multiple times. Both our Wifi and 4G connections work fine with all other apps. I even tried installing a different app, Square for Retail; same errors.

Contacted Technical Support, provided the screenshots and video they asked for, and never got a call or email back....

Tried installing the latest version on a spare cellphone as well and it does the same thing, but gives a different error:

Error Syncing

We are unable to load Square. Please try again or contact Customer Support if you continue to experience issues. Error code: CB4

Is anyone else experiencing issues with Version 5.79? Has anyone found a fix?

I'm experiencing this on a brand new 9th generation iPad with cellular that I just purchased from Apple. I keep getting error code FD4, on both cellular AND Wi Fi. Safari is able to load things just fine...so I've got internet.

Square says its not their issue but a networking one. all my devices failed loading after the update. I am using my friends phone which has the old version until i can figure it out.
