1. Introduction to ProtonMail and Common Issues
ProtonMail offers unparalleled security by encrypting emails, but sometimes users face ProtonMail not working problems that impact usability. These can range from minor annoyances like delayed email loading to more severe issues like complete login failures.

Common complaints include:

Unable to log into ProtonMail

Emails not sending or being received

Attachments not uploading

App crashes or slow performance

Sync errors between ProtonMail and third-party apps

Understanding these problems and their underlying causes is the first step toward resolving them effectively.

2. Understanding ProtonMail Not Working Problems
Before diving into fixes, it’s essential to understand why these issues occur. The most frequent reasons behind ProtonMail not working problems are:

Internet connectivity issues

Browser incompatibility or outdated apps

Server outages or maintenance

Misconfigured settings

Conflicts with VPN or firewall

Storage limits exceeded

Technical glitches on the ProtonMail platform

Identifying the root cause helps you apply the right solution quickly and efficiently.

3. Step-by-Step Troubleshooting Guide
3.1 Check Internet Connection
Sometimes, the simplest step is overlooked. A weak or unstable internet connection can cause ProtonMail not to load or sync correctly.

How to check:

Try opening other websites or streaming a video to verify connectivity.

Restart your router or switch from Wi-Fi to mobile data.

Run a speed test to ensure sufficient bandwidth.

If your internet is stable and fast, move to the next step.

3.2 Browser Compatibility and Cache Clearing
ProtonMail works best on modern browsers like Chrome, Firefox, Edge, and Safari. If you’re using an outdated or unsupported browser, issues are inevitable.

Solution:

Update your browser to the latest version.

Clear cache and cookies, which can accumulate corrupted data over time.

How to clear cache in Chrome:

Click on the three dots in the upper right corner.

Go to “More tools” > “Clear browsing data.”

Select “Cached images and files” and “Cookies and other site data.”

Click “Clear data.”

After clearing cache, restart your browser and try logging into ProtonMail again.

3.3 Update Your ProtonMail App
If you use the ProtonMail mobile app or desktop client, ensure it’s updated to the latest version.

Go to your device’s app store (Google Play or Apple App Store).

Check for ProtonMail updates and install them.

Restart the app and check for improvements.

Outdated apps are often incompatible with ProtonMail’s server changes, leading to failures.

3.4 Verify Server Status
ProtonMail sometimes experiences server outages or scheduled maintenance, which can cause temporary service interruptions.

How to check:

Visit ProtonMail’s official Twitter or status pages to see announcements.

Use third-party outage monitoring sites to verify service status.

If the servers are down, wait for ProtonMail to restore service.

3.5 Disable VPN or Proxy Services
VPNs and proxies can interfere with ProtonMail’s connections, especially if they block certain ports or IP addresses.

Steps:

Temporarily disable your VPN or proxy.

Attempt to access ProtonMail again.

If disabling fixes the problem, consider configuring your VPN to whitelist ProtonMail or use a different server location.

3.6 Review Account Settings and Quotas
Exceeding your storage quota or misconfigured filters can cause email delivery and synchronization issues.

Check your account settings:

Review filters and rules that might be moving emails to spam or other folders.

Check if your account is locked or suspended for any reason.

4. Fixing Specific ProtonMail Problems
4.1 Login Issues
If you can’t log into ProtonMail:

Confirm you’re using the correct email and password.

Use the “Forgot Password” option if necessary.

Clear browser cache or try a different browser.

Ensure 2FA (Two-Factor Authentication) is correctly set up if enabled.

Disable VPN and firewall temporarily.

4.2 Email Sending or Receiving Failures
If emails are stuck in the outbox or you don’t receive emails:

Check your internet connection.

Verify the recipient’s email address.

Review ProtonMail’s storage limits.

Make sure you’re not blocking the sender or domain.

Disable VPN if active.

4.3 Attachment Problems
Attachments may fail to upload or download due to:

File size exceeding ProtonMail’s limit (25 MB).

Network instability.

Browser incompatibility.

Try compressing large files, switching browsers, or reconnecting your internet.

4.4 Sync Issues with Email Clients
If you use ProtonMail Bridge or connect ProtonMail to external clients (Outlook, Thunderbird), sync problems can arise.

Ensure Bridge is up-to-date.

Check account credentials and app passwords.

Reinstall or reset ProtonMail Bridge.

4.5 Two-Factor Authentication Errors
If 2FA codes aren’t accepted:

Verify the time and date settings on your device are correct.

Resync your authenticator app.

Use backup codes if locked out.

5. Advanced Solutions
If basic troubleshooting fails, consider the following:

Clear DNS cache: On Windows, run ipconfig /flushdns in Command Prompt.

Reset browser settings: Restore defaults to remove problematic extensions or settings.

Try a different device: This can isolate if the problem is device-specific.

Reinstall the ProtonMail app: Sometimes a fresh install fixes persistent bugs.

6. When to Contact Support
