Error testing Anthropic API Key: CORS requests are not allowed

I’m new to UI.Vision. I set up an Anthropic account and have $5 credit for my keys. I think I gave them my credit card, but I think the $5 credit came for free. Not sure. First key didn’t work anywhere in UI.Vision, so I created another one which also doesn’t work. It did work in a curl command entered in Windows PowerShell (windows 11, home pc). But in Ui.Vision Chrome plugin, it doesn’t work with aiComputerUse command nor with the test button on the Settings > AI(New) tab (i.e. submitting the default prompt to Claude) where I have been very careful to enter the key and press Save. (key disappears, of course) then test fails with this error, which is also what I get when stepping through an otherwise working script and get to aiComputerUse. Have tried a myriad of things for hours, including restarting chrome and UI.Vision and entering they key and saving it again.
A deep thought Gemini report thinks it is because Anthropic is blocking the call from the Chrome extension. I’ll be glad to post the report and share a link to it if someone thinks that would be helpful. The error is below:

Line 2: E352: Anthropic API returned error: Error: 401 {“type”:“error”,“error”:{“type”:“authentication_error”,“message”:“CORS requests are not allowed for this Organization because of its settings. If you believe this in error, contact support at https://support.anthropic.com/.”}}

I just tested in Chrome and all works fine. Strange.

Can you maybe try uninstalling and reinstalling Ui.Vision? Does that help?

Or try in Firefox - Do you see the same issue?

Experiencing same error on both Chrome and Firefox and after reinstall
