Wallabag can't retrieve contents of the article (edn.com)

[nataloko]

Before submitting the issue, please read:
If wallabag can't parse / extract content for a given link, please first read the documentation about it:
http://doc.wallabag.org/en/user/errors_during_fetching.html#how-can-i-help-to-fix-that

We have a lot of requests about fetching config issue. It'll help us A LOT if you give a try to fix it on your own following the doc.
If you failed to fix it yourself, tick the following boxes:

• I've tried myself without success
• I've replaced HOST in the issue title with the host of the URL that can't be fetched (ie: nytimes.com, 20minutes.fr, bbc.com, etc.)

Content related:

• URL: https://www.edn.com/bootstrapping-your-op-amp-yields-wide-voltage-swings/
• wallabag version: 2.4.3

Describe what's wrong:

Wallabag can't retrieve contents from edn.com at all, I've tried several articles and in all of them I get a "wallabag can't retrieve contents for this article" message.

I'm using the wallabag.it service so I don't have access to logs etc; I've tried the f43.me test and I get some curl timeout error but I don't know what to do with that information.

I tried to solve this issue. But my config only works with FulltextRSS. :-(
fivefilters/ftr-site-config#1138

Wallabag/f43.me still throws a timing error:
Request throw exception (with no response): cURL error 28: Operation timed out after 10001 milliseconds with 0 bytes received

I think that could be a cloudflare thing or something similar?
