• wallabag version: 2.6.14-dev (wallabag.it instance)

Describe what's wrong:

On wallabag.it, since the beginning of August 2025 (the last fetching that worked well was on 2025-08-05 and the first that did not was on 2025-08-06), fetching article from https://www.lemonde.fr behind their paywall does not work anymore, in the sense that the fetched article entry is just empty (no title, no content, c.f. screenshot below).

I have tried refetching articles from the web interface without success (the interface tells me that content fetching failed).

I have checked my credentials that I registered in wallabag.it (I have a paid subscription for this journal website) and they are correct. I also tried to remove my credentials from wallabag and fetch a free article (link above) but I got the same problem.

Since I am using wallabag.it and not self-hosting, if I correctly read the documentation, I do not have access to the logs to investigate the issue.

Eventually, as stated in the documentation, I also tried to use https://f43.me/feed/test to do some test but the web site is down (I get a "502 Bad Gateway" error).

Before August 2025, it used to work without any issue.

I have linked an example article above which is freely available even without a paid subscription for testing.

Thanks in advance
