- Ensure mobile data access is enabled for the Gmail app, and that data saver mode is turned off.
- Signing out of Gmail and signing back in can help resolve connection errors.
- Consider clearing the Gmail cache data or reinstalling the app on your phone if the error persists.
Try Basic Fixes
- Temporarily disable VPN: Your VPN connection may interfere with Gmail’s internet access and cause issues. If so, disabling your VPN connection should resolve the error. If this solves your problem, continue using Gmail without a VPN or switch to a more reliable VPN service.
- Check if Gmail is down: It’s not uncommon for services like Gmail to experience server outages at times. When this happens, Gmail may not work as expected on your Android or iPhone and show unusual errors. You can visit a website like Downdetector to see if Gmail servers are down.
Fix 1: Enable Mobile Data for Gmail (iPhone)
Your iPhone lets you manage mobile data permissions for each app individually. If you’ve previously turned off mobile data access for Gmail, it will display the “No connection” error when your iPhone is not connected to a Wi-Fi network.
Open the Settings app > scroll down and tap on Gmail > enable the toggle for Mobile Data > reopen the Gmail app . Now, it should not show any errors.
Fix 2: Turn Off Data Saver Mode
Have you enabled data saver mode on your phone? This mode can sometimes affect an app’s ability to connect to the internet. To avoid this, turn off your phone’s data saver mode when not needed.
On Android
Step 1: Open the Settings app > tap on Connections .
Step 2: Tap Data saver > turn off the toggle for Turn on now .
On iPhone
Step 1: Open the Settings app on your iPhone > tap on Wi-Fi .
Step 2: Tap the info icon next to your Wi-Fi network > turn off the toggle for Low Data Mode in the following menu.
Step 3: If you’re using Gmail on mobile data, return to the Settings page and tap Mobile Data .
Step 4: Tap Mobile Data Options > turn off the toggle for Low Data Mode .
Fix 3: Sign Out and Sign Back In
Another reason Gmail may have trouble communicating with its servers and show the “No connection” error is if there’s an issue with your account. To fix this, try signing out of the Gmail app and signing back in using these steps:
On Android
Step 1: Open the Gmail app > tap your profile picture at the top right corner > select Manage accounts on this device .
Step 2: Select your Google account from the list > tap on Remove account > select Remove account again to confirm.
On iPhone
Step 1: Open the Gmail app > tap on your profile icon at the top right corner > select Manage accounts on this device .
Step 2: Select Remove from this device for your account > select Remove to confirm.
Add your account to the Gmail app again and see if the error persists.
Fix 4: Clear App Cache (Android)
Clearing the cache effectively fixes issues caused by corrupt or outdated temporary app files. So, if Gmail still shows the “No connection” error, try clearing its cache data using these steps:
Step 1: Long press the Gmail app and tap the info icon from the resulting menu.
Step 2: Go to Storage and tap Clear cache at the bottom.
If nothing else works, there may be a problem with some of the core app files or you might be using a buggy version. In such cases, uninstalling and reinstalling the Gmail app should help fix the error.
