Original GitHub issue: https://github.com/floccusaddon/floccus/issues/804

I have Nextcloud setup through an Apache reverse proxy, so far everything for standard Nextcloud is working as intended. I get E17: Network Error when I try to sync to Nextcloud when using the Chrome client on Brave. I don't have any issues logging into Nextcloud with the Nextcloud login flow feature. The issue doesn't show when using Firefox and I can sync my bookmarks.

To Reproduce
Steps to reproduce the behavior:

  1. Setup Nextcloud behind reverse proxy
  2. Try to sync the chrome client

Expected behavior
Bookmarks should sync properly

Desktop (please complete the following information):

  • OS: Windows10
  • Browser: Brave
  • Browser Version: Version 1.19.88 Chromium: 88.0.4324.96
  • Floccus version: 4.4.9
  • Floccus sync method: Nextcloud

Server (please complete the following information):

  • OS: Ubuntu Server 20.04
  • Nextcloud version: 20.0.6
  • Bookmarks app version: 4.0.6

Note: Please write down the actual version numbers instead of writing 'latest'.

Debug log
When I try to export a debug log from the plugin the file is empty.

Additionally, All testing was done over a VPN as not to cause issues with local DNS. That is an issue I will solve later.

Can you try inspecting the network requests as follows?

Firefox

  • Go to about:debugging -> This firefox
  • click on inspect button next to floccus entry
  • go to the network tab in the inspector tab
  • trigger a sync by clicking on sync now for the account of your choice.
  • check the failing network requests

Chrome

  • Go to chrome://extensions
  • enable Developer mode
  • click on dist/html/background.html button in floccus' entry next to "Inspect views: "
  • go to the network tab in the inspector window
  • trigger a sync by clicking on sync now for the account of your choice
  • check the failing network requests

I'm not sure if the extension update fixed the issue or If the cache was changed. In Firefox I had it set to always clear page caches. But it's working now.
