Before jumping into fixes, understanding the root cause helps you choose the right solution:

Since the error says "lost connection to your browser," the browser itself is often the culprit.

Pro tip: Try opening the Web UI in an Incognito/Private window. If it works there, the problem is definitely your cache or extensions.

The error is not a network failure; it is a local interface rendering failure. The "solid paper" consensus is that the WebUI framework within uTorrent is fragile. Clearing the cache usually fixes it temporarily, but moving to a modern client (qBittorrent) fixes it permanently.
