I recently updated to 22.214.171.12402 and it seems to have broken our action menu items that call to a webserver.
for instance I have a test AMI that has “http://our.webserver:9999/” under the URL field.
Calling this for a selected entity will yield this 400 error:
The browser (or proxy) sent a request that this server could not understand.
Up until the update, this worked fine. Any idea what could have changed? Is the URL signature different now?
