Testing Your Connection​

After entering your settings, Aerion will attempt to connect to the server. If the connection fails:

  1. Double-check the server hostname and port
  2. Verify your username and password
  3. Ensure the security setting matches your server's requirements
  4. Check if your firewall is blocking the connection

Troubleshooting​

"Connection Refused" Error​

  • Verify the server hostname is correct
  • Check if the port is correct (993 for IMAP SSL, 465 or 587 for SMTP)
  • Ensure your firewall allows outbound connections on these ports

"Authentication Failed" Error​

  • Confirm your username (usually your full email address)
  • Ensure you're using an app password if 2FA is enabled
  • Check if your provider requires enabling IMAP access in settings

"Certificate Error"​

  • Ensure the security setting matches your server
  • For self-signed certificates, you may need to add an exception
  • Contact your server administrator for the correct SSL/TLS settings
