Mobile fax, no Internet connection but there is.

[Fozzie66]

Hi deskjet 4100. 3 days ago mobile  fax worked 100% on my s23 mobile.

Today  the hp smart app is saying no Internet  connection.  However  there is Internet  connection definitely!

Uninstalled hp smart  and reinstalled and set up printer  again.  Still says no Internet  connection. Re- booted all equipment.  Still no joy. Why hp smart mobile  fax not working? Feels like hp is blocking me, is that possible? And  if so why? Used uk mobile  2 days ago to send fax to normal  fax machine in my home to BT landline,  (digital  landline  now). Mobile  fax on app keeps saying  no Internet  connection.

Please help.

Thank you.

Hi @Fozzie66,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I understand you have trouble with the HP Deskjet 4100 series printer, using HP Smart Mobile Fax on a Samsung S23 (Android). Previously working perfectly, now shows “No Internet Connection” You’ve already reinstalled HP Smart, rebooted, and confirmed internet access.

1. Log Out and Back Into HP Smart

Sometimes your account session gets corrupted.

• In the HP Smart app > Tap your profile icon > Sign Out
• Close the app completely.
• Relaunch, sign in again.
• Try Mobile Fax again.

2. Check App Permissions

On your Samsung S23, check that HP Smart has the correct permissions:

• Go to Settings > Apps > HP Smart > Permissions
• Ensure Network access, Storage, and Background data are enabled.

3. Test Over Wi-Fi vs. Mobile Data

Switch between:

• Wi-Fi and Mobile Data (4G/5G)
• Sometimes, one network path may be blocked from accessing HP’s fax servers.

I hope this helps.

Take care and have a good day.
