PubCoder needs to verify updates and license informations online from time to time. Normally this is not a problem since once the license verification is ok, the software can work without another verification for quite some time, so you can safely work offline.

Anyway, you will need an active Internet connection to log in to PubCoder the first time you launch it and connectivity issues may prevent you from using the software.

If you are sure your computer is connected to the Internet, but PubCoder refuses to connect, this is probably a proxy issue. PubCoder is able to use your system proxy configuration automatically on both Mac and Windows, but sometimes a misconfiguration in the “WinHTTP” proxy settings on Windows can lead to this error:


If your Windows PC is behind a proxy, check your proxy settings in Start → Control Panel → Network and Internet → Internet Options → Connections → LAN Settings, then, follow these instructions to apply the same settings to WinHTTP connections:

  • Open a command prompt in administrative mode (hit start icon, type cmd, then hit Ctrl+Shift+Enter)
  • Type netsh.exe winhttp import proxy source=ie in the command prompt (hit enter to confirm)
  • Your new configuration should be displayed. You can now close the command prompt window and launch PubCoder.
