@Zina25, Welcome to the HP Support Community!
Thanks for reaching out about your query regarding Mobile Fax Connection Issues!
We're thrilled to have the opportunity to assist you and provide a solution.
When encountering a "Can't connect to server" message while trying to fax from a mobile device using the HP Smart app, there are several steps you can take to resolve the issue:
Network Connection:
- Ensure your mobile device is connected to a reliable Wi-Fi or cellular network. Weak signals or disruptions can prevent the app from communicating with the server.
Application Updates:
- Check if there is an update for the HP Smart app. Outdated versions might not function correctly with current server configurations.
App Refresh:
- Close the HP Smart app completely and reopen it. Sometimes a fresh start can resolve temporary glitches.
Reboot Device:
- Restart your mobile device to fix any temporary settings or connectivity issues.
Re-login:
- Log out of the HP Smart app and log back in. This can reestablish a fresh connection to the server.
Firewall and Security Software:
- If you're using a secured network, ensure that the app is not being blocked by any firewall or security software.
Server Status:
- Occasionally, server-side issues can occur. Check HP's website or contact their support to see if there are any known outages or maintenance work being done.
Hope this helps!
Take care, and have an amazing day!
