If you install iQO2 on a company computer; you may get the 'connection failed' message due to the company firewall or proxy server that restricts access to parts of the web.

To solve this problem you must create rules to allow access to the iQO2 server. This is an advanced step best performed by someone experienced with configuring firewalls and proxy servers. If you haven't done this before, consider to contact the IT specialist in your company.

Ports used by iQO2:

  • Port 1433: standard sql server
  • Port 443: https
  • Port 587: smtp server
  • Port 110: pop3
