Common Errors

  • Open FAQ in new window I get an internet error 12157 or 12029 when trying to activate POP Peeper or other situations (e.g. Oauth2)
  • These errors can have a similar reason, usually because the system's SSL libraries are not enabled correctly. Here's how to fix this:

    1. In the Windows start menu, type and open Internet Options
    2. Select the Advanced tab
    3. Scroll the list to the bottom and make sure the following is enabled:
      • TLS 1.2
    4. Press OK

    If this doesn't resolve the issue, check that any security related software (e.g. 3rd party firewall) is not blocking POP Peeper's internet access.
