First, make sure you are attempting to use a valid link. If you are using a bookmark, try getting to the site another way as bookmarks can cause this error.
Next, if you are using Safari on a Mac, first to make sure your browser is not blocking all cookies, which can prevent NetID login from functioning properly.
Next, completely restart the browser so that all previous windows and tabs have been closed. In some cases, this alone can fix the issue. If this does not work, then the issue can usually be resolved by clearing your browser's cache and cookies.
