Proton Mail Not Working on iPhone? How to Fix It (2025 Guide)
Introduction
Proton Mail is one of the most secure email services available, but iPhone users may occasionally experience syncing issues, login errors, or app malfunctions. If your Proton Mail is not working on your iPhone, don’t worry most problems can be fixed in a few minutes. This guide covers the most common causes and effective solutions to get your email working again.
Proton Mail Not Working on iPhone? How to Fix It (2025 Guide)
1. Check Your Internet Connection
Before troubleshooting anything else, make sure your iPhone is connected to a stable internet connection.
- Switch between Wi-Fi and mobile data.
- Restart your modem or router.
- Toggle Airplane Mode on and off to reset the network.
If the connection is unstable, Proton Mail may fail to sync or load new messages.
2. Restart Your iPhone
A simple restart often resolves temporary system glitches.
- For iPhone X and newer: Hold Volume Up + Side button, then slide to power off.
- For older models: Hold the Power button until you see the slider.
Turn the phone back on and reopen Proton Mail to check if it works.
3. Update the Proton Mail App
Outdated app versions may be incompatible with recent iOS updates.
Steps:
- Open the App Store.
- Tap your profile icon.
- Check for updates and install the latest version of Proton Mail.
This fixes bugs, performance issues, and compatibility problems.
4. Update Your iPhone’s iOS Version
Running an older iOS version can cause app crashes or syncing errors.
To update iOS:
- Go to Settings → General → Software Update.
- Install any available update.
After updating, launch Proton Mail again.
5. Check Proton Mail Server Status
Sometimes the issue isn’t on your iPhone the Proton Mail servers may be temporarily down. Search online for “Proton Mail server status” or check Proton’s official status page. If the service is down, you’ll need to wait until Proton resolves the issue.
6. Enable Background App Refresh
If Proton Mail cannot refresh in the background, new emails may not appear.
Steps:
- Go to Settings → General → Background App Refresh.
- Ensure it’s turned ON for Proton Mail.
This allows the app to sync emails even when not opened.
7. Check Notification Settings
If Proton Mail works but notifications do not appear, adjust notification settings.
Steps:
- Go to Settings → Notifications.
- Select Proton Mail.
- Enable Allow Notifications and choose your preferred alert style.
This ensures you get real-time email notifications.
8. Re-Add Your Proton Mail Account
If you are using Proton Mail through Apple Mail instead of the app, incorrect settings may cause issues.
Steps to remove and re-add:
- Go to Settings → Mail → Accounts.
- Select your Proton account and remove it.
- Re-add using the proper IMAP/SMTP settings provided in Proton Mail Bridge (for paid accounts).
Free Proton Mail plans do not support third-party mail apps without Proton Mail Bridge.
9. Clear Proton Mail App Cache (If Available)
Some versions of the Proton Mail app offer a cache-clearing option.
Steps (if supported):
- Open Proton Mail.
- Go to Settings → Privacy & Security.
- Tap Clear Cache.
This can fix freezing, lag, and loading problems.
10. Reinstall the Proton Mail App
If none of the above works, reinstalling the app may resolve corrupted files.
To reinstall:
- Long-press the Proton Mail app → tap Delete App.
- Go to the App Store and reinstall Proton Mail.
- Log in again.
Make sure your login credentials and two-factor authentication (2FA) are accessible before uninstalling.
11. Disable VPN or Change VPN Server
Proton Mail is privacy-focused, but certain VPNs may interfere with connectivity.
Try:
- Turning off the VPN temporarily.
- Switching to a different server.
- Using Proton VPN (more compatible with Proton Mail).
12. Check Two-Factor Authentication Settings
If you recently changed devices or authentication apps, your 2FA may not sync correctly.
Open your authenticator app and make sure the time settings are correct. Incorrect time sync can block login attempts.
Frequently Asked Questions (FAQ)
Q1. Why is Proton Mail not loading on my iPhone?
This is often caused by poor internet, outdated app versions, or background refresh being disabled. Updating the app and checking your network usually fixes the issue.
Q2. Why am I not receiving Proton Mail notifications on iPhone?
Check your iPhone notification settings and ensure Background App Refresh is turned on. Also make sure Low Power Mode is not limiting app activity.
Q3. Can I use Proton Mail in the Apple Mail app?
Yes, but only with Proton Mail Bridge, which requires a paid Proton plan. Free accounts must use the official Proton Mail app.
Q4. Does Proton Mail work with VPN on iPhone?
Yes, but some third-party VPNs can block or slow down Proton Mail. Switching servers or using Proton VPN usually solves this.
Q5. What if Proton Mail still doesn’t work after troubleshooting?
Contact Proton Support, reinstall the app, or check for server-side outages. In rare cases, your account may need a security reset.
Q6: I’m getting a “Connection Timed Out” error. What does this mean?
This indicates your iPhone cannot establish a connection to Proton’s servers. The cause is almost always your local internet connection, a VPN, or a firewall. Check your Wi-Fi/mobile data and try disabling your VPN first.

The Right SEO Agency for Hospitality: Key Factors to Consider
Choosing the right seo agency for hospitality can feel overwhelming. There are so many agencies promising top rankings, more traffic, and higher bookings. Every agency claims to deliver fast results, but not every SEO agency for hospitality truly understands the unique challenges of the hotel and travel industry.
Hotels, resorts, boutique stays, and travel brands have very specific marketing needs. The way people search for hotels is very different from how they search for other services. Travelers look for locations, amenities, experiences, reviews, pricing, and availability often all at the same time. Because of this, a general SEO approach is not enough. You need a specialized SEO agency for hospitality that understands booking behavior, seasonal trends, and destination-based searches.
