(Not sure whether this is related to issue #490)

Context

I installed and configured AIL, Ail splash manager, Tor, i2P and squid, but all crawled domains seems to be "down", when they really aren't.
I use the tor proxy provided by The torproject.

As far as I know, Tor is working as expected:

curl --socks5 localhost:9050 --socks5-hostname localhost:9050 -s https://check.torproject.org/ | cat | grep -m 1 Congratulations | xargs
# Congratulations. This browser is configured to use Tor.

Also the squid proxy works

curl --proxy "http://172.17.0.1:3128" "http://google.it"

How can I solve the errors or at least continue the debugging?

Thanks in advance

It is solved!

The problem was a bug in scrapy introduced after 2.5.1 version, and should be solved in version 2.6.2 as mentioned here.

At the time being right now (22 days after that comment), the 2.6.2 version is not available yet via pip install scrapy==2.6.2, so the workaround until that version is available can be either download directly from the branch o downgrade to 2.5.1 version. The downgrade procedure can be seen below.

# Don't forget to activate the AIL virtual environment
cd ail-framework/AILENV/bin/ && source activate
pip install scrapy==2.5.1
#Just in case you had the previous one
pip install scrapy-splash=0.8.0
