Difficult to say without seeing your full sketch, but you shouldn’t be using port 8080 with the Blynk IoT cloud servers.

When you post serial output, and when you post your full sketch, please don’t post screenshots.

Instead, copy and paste the text and place triple backticks at the beginning and end so that it displays correctly.

Triple backticks look like this:

But I have my doubts about whether this is the sketch which produced the serial output in post #1
