Restart your modem or router.
Switch between Wi-Fi and mobile data if possible.
Run an internet speed test.

A stable connection is required for Roadrunner email to sync correctly.

Step 2: Verify Roadrunner Email Server Settings

Incorrect server settings are a major reason for Roadrunner connection failures.

Port	993
Security	SSL/TLS

Step 3: Restart Your Device and Email Application

Sometimes temporary glitches can interrupt the connection between the email client and server.

Close your email application completely.
Restart your computer or smartphone.
Reopen the application and test the account again.

This simple step often resolves minor sync problems.

Step 4: Disable Firewall or Antivirus Temporarily

Security programs may block incoming or outgoing email connections.

To test this issue:

Temporarily disable your firewall.
Pause antivirus email scanning.
Reopen your email client.
Attempt to send or receive mail.

If the connection works afterward, add your email application to the firewall exception list.

Step 5: Update Your Email Application

Using outdated software can create compatibility issues with Roadrunner servers.

Update Common Email Apps

Microsoft Outlook
Apple Mail
Mozilla Thunderbird
Android Mail
iPhone Mail App

Install the latest updates and restart the device afterward.

Step 6: Reset Your Roadrunner Password

Authentication failures can occur if your password has expired or changed.

Password Reset Tips

Use the official password recovery page.
Create a strong password with letters, numbers, and symbols.
Update the password on all connected devices.

After resetting the password, remove and re-add the account if necessary.

For password recovery assistance, call 1-888-400-6145 (Toll Free).

Corrupted account settings may prevent successful server communication.

Reconfigure the Account

Remove the existing Roadrunner account from your device.
Restart the device.
Add the account again using updated server settings.

This process refreshes the account configuration completely.

Step 8: Check for Server Outages

Sometimes the problem may not be on your device.

Signs of a Server Outage

Email delays occur everywhere
Authentication errors appear suddenly

Wait for some time and try again later if a server outage is occurring.

Step 9: Clear Cache and Temporary Files

Restart the email client

Step 10: Scan for Malware or System Issues
