Connection Closed rendering Facebook page

[rmassidda]

An exception is raised inside generate_soup method.
This seems to happen only with Facebook pages, I isolated the get/render part of the code and it runs smoothly with other websites.
Could this be related to the parameters of Retry?

Raised exception:

Mhhh, I'm not sure, it looks like the connection isn't working, it might be a pyppeteer issue or it might be related to the Retry settings or something else in requests-html. I can't recreate the issue so I can't elaborate it forward, i suggest you ask directly at their githubs.
If you find anything or can give me more details on how this issue arises, I'll leave the issue open

So i started getting the same error a few days ago and I've been working on either a fix or a workaround.
It appears on the Pyppeteer issue page [1] so it seems not to be my fault but I can't actually find a working fix.
I'm actually thinking about changing the rendering engine for JS, but right now I don't have much free time, maybe I'll be working on it in the spring
