Release 30: Fatal Error - Unable to retrieve cookies

[maric193]

Am currently trying to find a working release. The latest currently send back the below error without opening the browser. The command was formatted like so:

.\PatreonDownloader.App.exe --url https://www.patreon.com/cw/[name]/posts --download-directory d:\downloads --use-sub-directories

(Error below)

2025-09-30 21:30:01.6652 FATAL Fatal error, application will be closed: System.Exception: Unable to retrieve cookies at UniversalDownloaderPlatform.Engine.UniversalDownloader.Download(String url, IUniversalDownloaderPlatformSettings settings) in F:\Sources\BigProjects\PatreonDownloader\submodules\UniversalDownloaderPlatform\UniversalDownloaderPlatform.Engine\UniversalDownloader.cs:line 138 at PatreonDownloader.App.Program.RunPatreonDownloader(CommandLineOptions commandLineOptions) in F:\Sources\BigProjects\PatreonDownloader\PatreonDownloader.App\Program.cs:line 128 at PatreonDownloader.App.Program.Main(String[] args) in F:\Sources\BigProjects\PatreonDownloader\PatreonDownloader.App\Program.cs:line 68

Release 27 is the closest to doing anything, but after I login it just sits there and does nothing. Closing the browser and trying run again produces an "Unable to retrieve cookies" error.

I have the same issue. Deleting the entire folder and using a fresh copy of release 30 doesn't change a thing.

Yeah I'm getting the same errors, any updates for this one?

If any of you are using Arch Linux, and have Chromium installed, you need to ensure that you explicitly have Google Chrome Stable installed as well.

I had the same issue, but after installing google-chrome-stable, the app is working and the browser window opens, logs in, crawls, and works fine.

if these issues happen on Windows, then I have no idea...

I'm running Windows 10 LTSC and have Chrome installed for things like this. It worked in the past, but not any more.

The command I've always used is: "D:\PatreonDownloader\PatreonDownloader.App.exe" --url "https://www.patreon.com/c/CREATOR/posts" --download-directory "F:\LOCATION" --descriptions --embeds --campaign-images --json

Just ran into this issue myself whilst running release 30 on Win 10 Pro version 22H2. The browser fails to load and it throws similar errors as mentioned above.

However it works flawlessly on my Windows 11 laptop - could this be a Windows 10 / dependency issue?
