The following methods would help you troubleshoot the no connection error on the Gmail app:

Check your internet connection

Internet is the fundamental utility for using Gmail and sending/receiving emails. You must check your internet connection before going any further. Run an internet speed test or open any website or application to ensure you have an active internet connection.

In case the connection is unstable or inactive, contact your ISP (internet service provider).

If having stable internet doesn’t solve your problem, move to the next troubleshooting methods.

Reset APNs

APN (Access Point Name) settings contain the necessary information for making internet connections on your phone.

APN settings are automatically set up in your phone, and altering them affects internet speeds across apps on the device.

These alterations can be either manual or done by third-party apps. Reset the APN settings to default to maintain a balanced flow of internet in Gmail and other apps.

To reset APN settings on iPhone to default go to Settings > Cellular > Cellular Data Network, then tap Reset Settings.

Use the following steps to reset APN settings to default:

TO reset APN settings on Android, go to Settings > SIM cards & mobile networks then select SIM card. Now tap Access point names or APN > Reset.

If you cannot reset APN settings to default, search for the APN settings for your ISP and save these in your settings.

Unblock data usage

Data saver, background data restrictions, and restrictions on Gmail can cause it to not connect with the server.

You can disable data saver in Settings > Network/Connectivity in both iPhone and Android phone.
