Research direction

The report names no project source file or test. Start by reproducing the failing fetch from inside the container, comparing direct curl with the wallabag request, and inspect the httplug/Guzzle and Graby log path shown. Done means the affected sites can be fetched without the reported error 500, with a regression check for the differing request behavior.

Description

In a new deployment of wallabag-docker-service on a raspberry pi I'm getting an error 500 when trying to fetch some sites:

If I make a direct curl https://www.viajeroscallejeros.com/que-ver-en-el-hierro/ from inside the container, it works perfectly.

I can fetch some addresses without problems, but some others I cannot fetch and I get an that error 500
