The classic quickbox.io site sails into the rainbow. We moved every remaining account to v3.quickbox.io for you, so there is nothing to migrate. Sign in with the same email and password, grab your new API key from the dashboard, and if you are on a subscription, add a payment method before your access date to keep your price.
The legacy quickbox.io license API is being retired. If your install stopped verifying or QBXWatcher asked you to re-verify, here's why, and the exact steps to move your license to v3.quickbox.io and get back online.
Two new tools land in the dashboard. Inter-Instance Transfer moves a whole folder tree directly from one of your servers to another, migration or load-balance, with no SSH and no relay, and a live cockpit to watch it. The Telemetry History Store keeps your server's metric history gap-free across restarts, deploys, and reinstalls, all on the box and never phoned home.
ruTorrent is great. qBittorrent is too. Here is when the migration is worth it, what you actually have to move, and how to keep ratios and tracker history intact.
