Hello 👋

Thank you for taking the time to open this issue with floccus. I know it's frustrating when software
causes problems. You have made the right choice to come here and open an issue to make sure your problem gets looked at
and if possible solved.
I'm Marcel and I created floccus and have been maintaining it ever since.
I currently work for Nextcloud which leaves me with less time for side projects like this one
than I used to have.
I still try to answer all issues and if possible fix all bugs here, but it sometimes takes a while until I get to it.
Until then, please be patient.
Note also that GitHub is a place where people meet to make software better together. Nobody here is under any obligation
to help you, solve your problems or deliver on any expectations or demands you may have, but if enough people come together we can
collaborate to make this software better. For everyone.
Thus, if you can, you could also have a look at other issues to see whether you can help other people with your knowledge
and experience. If you have coding experience it would also be awesome if you could step up to dive into the code and
try to fix the odd bug yourself. Everyone will be thankful for extra helping hands!
One last word: If you feel, at any point, like you need to vent, this is not the place for it; you can go to the forum,
to twitter or somewhere else. But this is a technical issue tracker, so please make sure to
focus on the tech and keep your opinions to yourself.

I look forward to working with you on this issue
Cheers 💙

HI @SuperSandro2000

are you sure about the floccus version and the bookmarks app version? Both versions ~~are quite old~~ have been around for some time and shouldn't cease to work suddenly. It's more likely you got one of the recent updates to either, I think.

Yes, unless I am mixing things up.

The Floccus browser extension displays the following version in the bottom left

which matches the version available on the chrome webstore https://chromewebstore.google.com/detail/floccus-bookmarks-sync/fnaicdffflnofjppbagibeoednhnbjhg

The bookmarks app got an update in the meanwhile and I also updated to nextcloud 28.

Mh. I cannot reproduce this with the following versions:

floccus 4.19.1
Sync method: Nextcloud Bookmarks
Chrome 120.0.6099.71
13.1.2
Nextcloud 26.0.9

But the nextcloud version shouldn't matter here. Are you sure the URL is correct?

@SuperSandro2000 commented on GitHub (Dec 15, 2023):

Are you sure the URL is correct?

Yes, I can see the requests in my nginx logs and there are no extra redirects except from http to https. If I paste the URL from the form into my browser url bar I am straight in my nextcloud.

I've just done some additional testing and it seems I also had an with nextcloud 28 incompatible app installed. My logging tab is currently not working, so I didn't notice it yet.

But even after fixing that I still can't log into floccus in chrome but in firefox with version 5.0.3 the log in succeeds but with a pop up that flocus wants to read all websites.

The error printed in the console in chrome is still the same as above. Maybe the update to 5.0.X in chrome will fix that.

Edit: I found a fix. If I add my nextcloud domain to site access under extension settings, things start to work. I think floccus should ask for the specific domain I am trying to log in in chrome, too.

Mmh, it's just, the floccus version you noted is out since July or even before that. I wonder what changed that it doesn't work anymore now?

it seems I also had an with nextcloud 28 incompatible app installed

Which app was that?

Could be chrome updates which tighten security or so. Or maybe the nextcloud update. I found one entry in the changelog which reads rather promising https://github.com/nextcloud/server/pull/40737

I wasn't able to reproduce with your chrome version though.

Or maybe the nextcloud update.

Did you update to Nextcloud 28 already? the ticket says you're on 27
