Hi,

I am not able to establish connection to Qlik Engine JSON API through jwt using Python.

Getting error "Cross-Site Websocket Hijacking attack prevention check failed. Possible Cross-Site Websocket Hijacking attack(CSWSH) discovered."

Please help me out in resolving the issue.

Regards,

Malar

Hey @Malar , which Qlik Sense on prem version are you using? If you are running Nov 2024 onwards, you need to add CRSF token to websocket url (plus you need to add a configuration into your JWT VP).
