This has been a frustration for a while - I am trying to figure out how to configure Notepad++ (now at v5.6.8 Unicode) to use a proxy server with a specific username and password when connecting to check for updates. At the moment I get a dialog stating:

curl error
couldn't connect to host

When setting up the Plugin Manager I have given it the proxy server address in the form: username:password@server-address and supplied the port in the separate box - which works (although somewhat uncomfortable as this exposes my username/password).

How can I achieve the equivalent with the main update configuration? I've searched extensively on both the Notepad++ wiki and Google with no success other than a possible reference to using a local proxy to force connections to gateway properly.

Notepad++ uses Generic Updater for win32 (it's free).

The updater is located here: C:\Program Files (x86)\Notepad++\updater Assuming you've used default installation path and running 64-bit windows and notepad++ 32-bit. If not look try here as well: C:\Program Files\Notepad++\updater\

What you need to do is start command line (e.g. Start->run->cmd OR Start->(search programs and files)->command) as administrator and execute the following lines:

1. cd /d C:\Program Files (x86)\Notepad++\updater
2. gup -options

This will bring up proxy settings dialog where you can enter your proxy address.

    Should be mentioned that the proxy settings of Notepad+ have to be empty to make this work.

  • I'm on the latest version (7.9.5) and I don't have the option of setting the credentials, just the url and port. None of the answers actually cover the specific "with username and password" part of the question. May 24, 2021 at 8:29

Notepad++ has added Set Updater proxy... command to the ? menu for setting the proxy of updater since v6.3.1.

Please refer to NotePad++ v6.3.1 Change Log.

  • Thanks for the update - makes this much simpler when you can get it through the client!

  • I can still find this option in v6.6.8.

After I completed the steps bellow, I was able to update the Plugin Manager and install new plugins like XML Tools:

  1. Go to Plugins > Plugin Manager > Show Plugin Manager

  2. Click on Settings.

    enter image description here

  3. Fill in the Proxy address and port - with your data

    enter image description here


Since it appears to be using curl, I tried setting the http_proxy environment variable and that seemed to work as well. I set it to something like

http://username:[email protected]:port/

Might be more compatible, central, and obvious than Generic Updater's internal config.

Note, curl also uses https_proxy and ftp_proxy environment variables. Doesn't appear to be needed for current versions of notepad++, but if you're setting one, you may want to set the others for future proofing (HTTPS is probably more important than FTP).

    Thanks for providing another option - guess it just depends what you're doing and how!

    This is the only answer that worked for me. And I didn't even need username and password, just domain and port.
