update plugin manager from 1.3.5 to 1.4.3, plugin manager report connection error

  • I update plugin manager from 1.3.5 to 1.4.3 on v6.9.2, plugin manager is unavailable, it always report connection error。

    could it be that you are using windows xp or linux and wine?
    Try switching protocol - in settings use http instead of https.


  • I got the same error.
    O/S: Win7 and I have enabled (checked) the Plugin Manager Settings -> “Force HTTP instead of HTTPS…” checkbox, but it doesn’t help.
    Any clue?

    • When I tried to use Plugin Manager 1.3.5 to update to Plugin Manager to 1.4.3, it errorred out, and I had to manually go download from the github releases directory myself, and overwrote my old PluginManager.dll, then reloaded NPP

    • When I tried to view the plugin list, like the other users, I saw “Download Error: There was an error downloading the plugin list. Please check your internet connection, and your proxy settings in Internet Explorer, Edge or Chrome.”

      • My Internet Properties proxy settings all work fine with all other browsers (including Chrome and IE), and I can get to external HTTP and HTTPS sites with no problems.
    • Clicked Plugin Manager > Settings > Force HTTP instead of HTTPS for downloading plugin list

    • OK > Close, then loading Plugin Manager again still didn’t show the list

    • Exit NPP. Reload NPP. Now Plugin Manager now shows the list.

    Looks like there may be a systemic problem in accessing the plugin list via HTTPS

  • Interesting. I went back to the Plugin Manager Settings, turned off Force HTTP..., and exited NPP. Then I went to %AppData%\Notepad++\plugins\config and deleted the PluginManagerPlugins.zip and .xml files. I reloaded NPP, and went to the Plugin Manager, and this time it did download the plugin list (config directory again has both the zip and xml files).

  • @Dave-Brotherstone :
    Could you have a look at these issues.
