urlopen error Tunnel connection failed: 403 Forbidden

[Devops warrior]

Hello Experts,

I have playbook which works fine since 6 months. It's started throwing tunnel connection failed, since yesterday morning. However the curl works fine. Can someone let me know if this is a bug or any other ways to bypass proxy?

curl -I https://10.97.7.198 -k

HTTP/1.1 200 OK
