(Bug report) Always error connecting to sync server after wrong DNS configuration once

Description

I have my own sync server, and set up syncing in my Trilium desktop app. It all worked great, until I made a mistake in DNS set up.
In short, the problematic set up was: Infinite redirect loop using status code 301. (It was due to an incorrect configuration of cloudflare by myself.)
The resulting behaviour is: trilium always fails to connect to sync server; on "sync" configuration page, clicking "test sync" will lead to an immediate popup saying "... too many redirects".

I can bypass the issue with commandline switch --disable-http-cache, and trilium will resort to sync. However, I have to enable this switch everytime when starting trilium, otherwise the problem re-occurs.

This has been an issue since original Trilium. It looks like clearing the DNS cache would resolve the issue, but I cannot find a way to do this. Hopefully this can be added as a button in "advanced" options page.

I'm not sure, but clearing the Electron cache might solve the problem.

Hi @SiriusXT , Thanks for the quick reply.
It seems to work, by only deleting ~/.config/TriliumNext Notes/Cache/. The upper-case name made this directory invisible in my previous search (it's lower-case in other places, e.g. ~/.local/share/trilium-data/).

But this not only happens for Linux desktop, but also on MacOS. The same directory does not exist on that location, and I don't have a clue on how to guess.

In fact, it is exactly because the issue happens on all platforms (well, I only have Linux and MacOS, but no reason it's different on Windows or elsewhere) that I raised this as a bug report.
