I am currently using an App Search instance for the backend and a React front end user interface based on elastic search-ui. The config for the SearchProvider element have the right authentication details (searchKey, endpointBase, and engineName).
I've been encountering a bit of a Heisenbug because sometimes, pulling up the search page sometimes triggers a alert box asking for a username and password. I can't figure out what the right username and password are, and that causes the search page to crash with a 404 error. However, the weird thing is this issue occurred on code that was working perfectly before. In addition, this bug also simply goes away after a while, after no changes have been made to the code. Help would be appreciated!
