Wallabager refuses to check URL

[Mereck13579]

Got a wallabag instance up and running, I can connect to it using the Android app without any issue.
On one (local network) computer I only managed to connect wallabager using the IP in HTTP, figured out it might have been a weird DNS issue.
But now I'm testing on my work PC and it just doesn't want to connect using the DNS name.
I enter the URL, hit "check URL" but the URL checked stays on "not checked" for some reason (on the following screenshot the permission checked got the "agreed", but refreshing the option page and trying again put it on "not checked")

If I copy and paste the URL in another tab, it works properly :

There is unfortunately nothing in the Chrome console when that happens:

And checking into the chrome extension manager, I can see the URLs being allowed for site access:

Wallabager version : 1.18.0
Wallabag version : 2.6.10
Chrome version: 131.0.6778.86

Hi,
Can you enable the debug mode at the end of the option page, then try again to validate the URL? Then give me the error result that should appear on the extension page (chrome://extensions/)?

Alright, I checked the other issue to see what might help you there.
Tried it again, refreshed page after going to the network tab (otherwise after entering, nothing happens, table stays empty).
The only new activity there is the "version" (the others are from the initial loading of the option):

Blurred request URL is the DNS address of wallabag.
Remote address is the IP address of the reverse proxy.

No error in the console when you click on the "Check URL" button?

"It depends"
Sometimes, when the "permission checked" turns to Agreed (but url checked is still not checked) I get this:

Otherwise, nothing, the console stays empty.

Could you have any extension that can interfere with it? Can you try it with a fresh profile/another browser like Firefox?

When I tried to link the Chrome extension to my hosted app.wallabag.it account in Thorium, I got this when I clicked "check URL":

But when I set the "Disconnect" extension to "unblock site" when the tab with the Wallabagger options page was open, I was shown this when I clicked "check URL":

When I entered my API keys, username and password, and clicked "get token", the extension worked. But sometimes I had to click the "Wallabag" icon twice for an article to be saved.
