### 1. ProtonMail Login Issues

A frequent problem users encounter is **[ProtonMail not working](https://hackmd.io/@protonmail/protonmail-not-working)** due to login difficulties. This issue can prevent you from accessing your inbox and using your email account.

### Common Causes:

Incorrect username or password: If you’ve forgotten your credentials or mistyped them, you won’t be able to log in.

Account locked or suspended: ProtonMail may temporarily lock your account due to security concerns or policy violations.

Two-factor authentication (2FA) issues: If you're using 2FA, an incorrect or unavailable authentication method can prevent access.

Browser-related issues: Problems with cookies, cache, or extensions can interfere with logging in.

### Solutions:

Verify credentials: Double-check your username and password. If you've forgotten your password, you can use the account recovery options to reset it. ProtonMail allows you to recover your account via your recovery email or recovery phrase.

Check for account lock or suspension: If ProtonMail suspects unusual activity, your account may be temporarily locked. Check your email inbox (if accessible) for any notifications from ProtonMail explaining the suspension. If the lock is due to suspicious activity, you may need to go through account verification to regain access.

Resolve 2FA issues: If you’re having trouble with two-factor authentication, make sure you’re using the correct method (such as Google Authenticator or an alternative 2FA app). If you’ve lost access to your 2FA method, ProtonMail will guide you through the recovery process using backup codes or recovery emails.

Clear browser cache and cookies: Sometimes, browser issues can prevent successful login. Clear your browser cache, cookies, and history to eliminate any old data that may be causing conflicts. You can also try using an incognito window or a different browser altogether.

### 2. ProtonMail Not Syncing with Devices

Another common problem is ProtonMail not syncing across devices. If you've been able to log in but find that your emails aren’t updating across your phone, tablet, or desktop, this can be frustrating.

### Common Causes:

Connectivity issues: If you're experiencing slow or intermittent internet connectivity, ProtonMail may struggle to sync your inbox across devices.

App-related bugs: If you're using ProtonMail's mobile app (iOS or Android), there could be bugs or glitches that prevent the app from syncing emails properly.

Email settings: Incorrect settings in the ProtonMail app or web interface could disrupt syncing.

### Solutions:

Check internet connectivity: Ensure you have a stable internet connection. Try switching between Wi-Fi and mobile data to see if the syncing issue persists.

Update the ProtonMail app: If you’re using the mobile app, make sure it’s updated to the latest version. App updates often include bug fixes that can resolve syncing problems.

Reinstall the app: If updating the app doesn't work, consider uninstalling and reinstalling it. This can help fix issues caused by corrupt app files.

Check ProtonMail settings: Log into your ProtonMail account via the web interface and check your email settings. Ensure that your settings allow for automatic syncing and that your inbox isn’t being filtered or set to offline mode.

### 3. Emails Not Sending or Receiving

One of the most frustrating problems is when ProtonMail is not sending or receiving emails. This can happen if your outgoing emails are stuck in the outbox or if incoming emails aren’t appearing in your inbox.

### Common Causes:

Server outages: Sometimes, ProtonMail may experience temporary server outages or technical issues that prevent email delivery.

Full inbox or storage limit: If you’re using the free version of ProtonMail, your account may have reached its storage limit, preventing the sending or receiving of new emails.

Spam filters: Emails may end up in the spam folder due to ProtonMail’s automatic filters or because your email address is being flagged as suspicious.

Incorrect email settings: SMTP/IMAP/POP settings may be misconfigured if you're using ProtonMail with a third-party email client.

### Solutions:

Check ProtonMail status page: Before troubleshooting, check ProtonMail’s status page (or social media) to see if there are any ongoing server outages or maintenance that might be affecting email functionality.

Free account storage: If you’re using the free plan and have reached your storage limit (500MB), consider upgrading to a premium plan or freeing up space by deleting old emails or attachments.

Check spam folder: Sometimes, legitimate emails are mistakenly flagged as spam. Check your spam or junk folder to see if the missing emails are there.

Verify email settings: If you're using ProtonMail with an email client, ensure that your SMTP/IMAP/POP settings are configured correctly. ProtonMail provides detailed instructions on setting up your account with external email clients.

Disable filters: Check your email filters to ensure no rules are preventing email delivery.

### 4. ProtonMail Mobile App Not Working

If you're using ProtonMail on your smartphone and find that the ProtonMail app is not working, you might experience crashes, slow performance, or issues with loading messages.

### Common Causes:

App bugs: Like any app, ProtonMail’s mobile version can sometimes have bugs that prevent it from functioning properly.

Operating system issues: In some cases, the problem could be with your phone’s operating system, rather than the ProtonMail app itself.

Outdated app: Running an outdated version of the app can lead to performance issues and bugs.

### Solutions:

Update the app: Ensure that you are running the latest version of the ProtonMail app. You can check for updates in the App Store (for iOS) or Google Play Store (for Android).

Restart your device: A simple restart of your phone or tablet can resolve many app-related issues by clearing temporary glitches or conflicts.

Reinstall the app: If the app is still not working, try uninstalling and reinstalling it. This can help eliminate issues caused by corrupted files.

Clear app cache: In Android devices, you can clear the app cache, which may help resolve any slowdowns or crashes.

### 5. ProtonMail Not Loading

In some cases, users may find that ProtonMail is not loading at all when they try to access the website or open the app. This can be a major inconvenience, especially if you need to access your email urgently.

### Common Causes:

Server downtime: ProtonMail may experience temporary server outages, preventing the platform from loading.

Browser issues: Problems with your browser, such as outdated software, incorrect settings, or conflicts with extensions, can stop ProtonMail from loading properly.

Network restrictions: Some networks may block ProtonMail or limit access to certain websites or services.

### Solutions:

Check ProtonMail status: Visit ProtonMail’s official status page to see if the issue is related to a server outage.

Clear browser cache and cookies: Clear your browser’s cache, cookies, and browsing history. This will ensure you’re loading the latest version of the ProtonMail site without old, conflicting data.

Try a different browser: If ProtonMail is not working on one browser, try using another. Sometimes, browser-specific issues or extensions can interfere with ProtonMail’s functionality.

Disable browser extensions: Some browser extensions, such as ad blockers or privacy tools, may prevent ProtonMail from loading correctly. Try disabling these extensions and see if ProtonMail loads properly.

### 6. ProtonMail Not Working with VPN

While ProtonMail is designed to be secure, some users experience issues when accessing it through a Virtual Private Network (VPN). A VPN can sometimes block or slow down ProtonMail’s ability to load properly.

### Common Causes:

VPN server issues: The VPN server you're connected to may be experiencing connectivity issues, affecting ProtonMail's performance.

IP restrictions: ProtonMail may block certain IP ranges that are associated with VPN servers, mistaking them for suspicious activity.

### Solutions:

Change VPN server location: Try connecting to a different VPN server or region to see if that resolves the issue.

Disconnect from VPN: If possible, try accessing ProtonMail without the VPN to determine if the VPN is causing the issue.
