The Wi-Fi needs a login or acceptance page first; until you complete it, secure sites fail with certificate or connection errors.
Chrome: Page Unresponsive — The following page(s) have become unresponsive. You can wait for them to become responsive or exit the page(s)

The page you tried to embed in an `` forbids framing through the `X-Frame-Options` header or CSP `frame-ancestors`.
Console: Refused to apply style from 'https://…/style.css' because its MIME type ('text/html') is not a supported stylesheet MIME type

Console: Uncaught (in promise) Error / TypeError / DOMException — unhandled promise rejection
A promise was rejected and no `.catch()` or `try/catch` handled it, so the browser logs it as an unhandled rejection.
Console: Failed to register a ServiceWorker: A bad HTTP response code (404) was received when fetching the script
The browser could not fetch, parse or install the service worker script, or the page is not allowed to register one (HTTPS and sc…

The user (or the browser/OS/policy) denied camera or microphone access, so `navigator.mediaDevices.getUserMedia()` was rejected.

`getUserMedia` found no camera or microphone matching the constraints — the device is missing, disabled or the constraints are to…
Console: NotReadableError: Could not start video source (camera in use by another app)

The server can’t produce a response in any format listed in the request’s Accept headers.
Chrome: This page isn’t working — example.com didn’t send any data. ERR_EMPTY_RESPONSE

Chrome: This page isn’t working — example.com redirected you too many times. ERR_TOO_MANY_REDIRECTS
The page keeps redirecting to itself or in a loop, so the browser gives up after about 20 redirects.
HTTP 407 Proxy Authentication Required
A proxy between you and the server requires credentials before it will forward your request.
HTTP 408 Request Timeout
The server closed the connection because the client took too long to send the complete request.
TypeError: Failed to fetch / NetworkError when attempting to fetch resource

RangeError: Maximum call stack size exceeded
A function called itself (directly or indirectly) too many times — usually infinite recursion.
Error: Too many re-renders. React limits the number of renders to prevent an infinite loop.
A state update runs during render, which triggers another render, which updates state again — forever.

A browser extension sent or received a message and the other side closed the channel without replying — almost always an extensio…
SecurityError: Blocked a frame with origin "x" from accessing a cross-origin frame.

Refused to load the script because it violates the following Content Security Policy directive
The page’s Content-Security-Policy doesn’t allow that script, style, image or connection source.
This Set-Cookie was blocked because it had the "SameSite=Lax" attribute but came from a cross-site response / SameSite=None requires Secure
The browser refused to store or send an auth/session cookie because of SameSite or Secure rules — so logins don’t “stick” across…
HTTP 404 Not Found
The server can’t find anything at the requested URL.
Refused to execute script from 'x' because its MIME type ('text/html') is not executable
The browser fetched a script but the server labelled it text/html (usually an error page), so it refused to run it.
Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/html"
A or dynamic import got HTML back instead of JavaScript.
AbortError: The user aborted a request. / signal is aborted without reason
A fetch was cancelled through an AbortController (or the browser cancelled it).
Console: SecurityError: Failed to execute 'toDataURL' / 'getImageData' on 'HTMLCanvasElement': Tainted canvases may not be exported
You drew an image from another origin onto a canvas without CORS permission, so the browser blocks reading pixels back out.
