Error: HTTPSConnectionPool(host='yoursite.scratch.my.salesforce.com', port=443): Read timed out. (read timeout=None)

Describe the bug

While running the cci flow run command to run the flow used to generate the data on the SF (using Snowfakery: https://snowfakery.readthedocs.io/en/latest/index.html#use-snowfakery-with-salesforce) org the following issue appears : Error: HTTPSConnectionPool(host='yoursite.scratch.my.salesforce.com', port=443): Read timed out. (read timeout=None).

• Python: 3.13.10
• CumulusCI: 4.6.0
• Corporate VPN connection is used.

Tried to switch off the firewall, it did not work.
Tried to find any way to set the timeout, but all the options did not work.

Reproduction steps

1. Install Python: 3.13.10
2. Install CumulusCI: 4.6.0
3. Create a Snowfakery recipe e.g. accounts.yml according to the instruction (https://snowfakery.readthedocs.io/en/latest/index.html#use-snowfakery-with-salesforce) + set the higher count attribute value and populate more fields.
4. Import the SF org using command: cci org import <sf_alias> <cci_alias>
5. Set that org as default using command: cci org default <cci_alias>
6. Outline the data load task in the cumulusci.yml:``` tasks:
   generate_accounts:
   description: "Generates Accounts"
   class_path: cumulusci.tasks.bulkdata.generate_and_load_data_from_yaml.GenerateAndLoadDataFromYaml
   options:
   generator_yaml: cci/ldv-recipes/accounts.yml

7. Try to run the task using `cci task run generate_accounts`
8. Explore the results.
Maybe that issue cannot be reproduced from the very first time.
