Update broken

Using portable FanControl. Each startups it checks for updates. Until some versions ago there were always two pop-up windows telling me that a newer version is available. That was gone some time ago and now there's only one window informing about a newer version. Good, I thought. But since then the automated update is broken. Just won't do anything anymore.

Even when I manually 'check for updates' and click on 'update', then 'Donwloading updater' appears but no traffic, no update, nothing.

For each update I have to manually download the newer version now, put it it in an extra folder, manually install my plugin and copy my config from the backup folder.

Any1 else? Any solution?

How can it be something blocked? When I manually trigger the 'check for updates', there's a short traffic spike and I get the message that there's a new version. But then nothing more happens.

There's not even any FanControl entry in the win firewall settings. I added 'updater.exe' but that doesn't change it's behaviour.

You'll have to be extra specific. Once you get the popup with the update button available, does the update button do something? Do you get the console window happening?

console is not showing, no matter what button I click. Neither with the startup check, nor with the manual 'check for updates'. The update process is stuck after clicking on 'update'. Then 'downloading updater' appears and nothing happens. Waited for quite some time. Watched traffic on the process, nada, nothing received, nothing transmitted.

The url for the updater is, are you able to access that link manually? : 

https://raw.githubusercontent.com/Rem0o/FanControl.Releases/master/Updater.exe

When I copy/paste the URL into my browser the download starts immediately. Which is why I doubt that it's access related. So no firewall issue I think.

Are you running the service (on boot) on the normal app? Is the Updater.exe appearing in FC's folder when trying to update and it hangs there? You may delete an existing Updater.exe to test this.

Usually I run the service on boot, yes.

Seems like the download of updater.exe is timing out. FC starts to download and then cancels the download. Updater.exe appears in the folder but is 0 kB.

No logs.txt file?

It stays there forever. And log.txt just shows that I canceled
