Common Errors

  • Open FAQ in new window SSL connection failed (certificate failed: self signed certificate (18))
  • This error is most common with personal domains. If you receive this error with a major ISP or email service, then it may indicate an issue with your local certificates; contact support for help.

    If you knowingly have a self-signed certificate, then you will need to add an exception for your mail host:

    1. From POP Peeper's main menu, select Tools / PPtweaker
    2. Select the Certificates page
    3. Type your email server address on a separate line (you may need to add your SMTP address if it's different); e.g. mail.example.com
    4. Press OK
