This error message occurs on my browser during a web interaction workflow. Workflow is below:

The top row of nodes connects to the web and goes through Microsoft authentication to log into my work account. This is necessary to access the URLs. Afterwards, I start a loop to iterate through each URL, which each downloads a PDF to my desktop. The goal is to automatically download all the PDFs with the click of a button.

The authentication works (The “Click Phone Call” node claims to fail, but it actually does work). The issue I’m having is after the authentication, when I want to change the page to the first URL. Instead of successfully navigating to the first URL, I get the error message about timeout. See the node with the ⚠ marker.

Can anyone recommend a way to fix this?
