Python 3.10/11 SSL: SSLV3_ALERT_HANDSHAKE_FAILURE

[valentinedwv]

Not fatal, but just an issue note:

Seems there is a issue with 3.10/3.11
python/cpython#103142

Mac Intel

and containers using
FROM python:3.11-slim
FROM python:3.10-slim

This url:

https://opentopography.org/sitemap.xml

gets redirected to:

https://portal.opentopography.org/sitemap.xml

If i just use https://portal.opentopography.org/sitemap.xml it works fine.

Thanks a lot for reporting @valentinedwv !

I can also see the same behavior on a Mac, also on Google Colab (Linux).

Not sure if there is something I can do here?
I'll check.
Thanks again.

Try running on python 3.09

@valentinedwv Thanks ! Finally I did
!pip uninstall -y scrapy !pip install Scrapy==2.6.3
and everything works fine !
