The question here is if localhost:1717 is the right address? Shouldn’t it be McNeel address?
This didn’t help: chrome://flags/#allow-insecure-localhost
The localhost:1717 is where the authentication process redirects to after you’ve signed in to your rhino account. Here the result is communicated to your Rhino instance.
Fiedler is displaying this:
HTTPS handshake to localhost (for #134) failed. System.IO.IOException The handshake failed due to an unexpected packet format
The default web browser was Edge. The three websites above could be accessed. Proxy was disabled. Rhino did run on the computer before. The problem appeared a few days ago.
I fooled around on the computer in a remote session for a while. In the end, resetting Edge fixed the problem. Before Resetting Edge, Chrome had the same problem. I don’t understand why.
