Problem to connect arduino to GCP Blynk server via raspberry

Hi everyone, I am working on a project for the school.
All my hardware I need is arduino, raspberry, and some sensors. My project is to use Blynk to transfer data from arduino to the GCP server (local blynk server on GCP) via raspberry.
But my current problem is that I cannot pass data from rasberry to GCP. Details are in the picture below. I hope the community will help my situation. Thanks

Is there a reason why you’ve marked your topic as solved?

If it isn’t solved then I’d start by providing all of the details that are requested when you create a “need help with my project” topic.
I’d also suggest copying and pasting any code, server logs etc rather than posting screenshots.


Sorry, my fault
