Please log in again to continue."** Sign in again. Your encrypted local history is untouched. **"Anonymous chat isn't available. Please log in to continue."** The account-free path is off for this session. Sign in, or create an account. **Login times out or the button stays busy.** Wait for "Please try again", then submit again. **Another tab signed in or out.** The app reloads before showing mixed-account state. Reload the tab if it looks stale. ## Models **"Unable to fetch models. Please try again."** Use **Retry** in the picker or the toolbar notice. Sending stays disabled until the catalog loads. **"Loading models..." for a long time.** Same cause. Check your connection and retry. **A model is marked Unavailable.** The row's own reason says why: inference temporarily disabled, the provider temporarily unavailable, or an outstanding balance (see below). **A model is marked Incompatible.** The chat holds Confidential or Encrypted history. Continue on a compatible model or start a new chat. ## Free Allowance **"You've used your free prompts for today."** The notice shows the reset time. Upgrade to keep going, or wait for the reset. **"Free access is unavailable for this account."** Use **Review account** to open Settings, or contact [support@trynito.ai](mailto:support@trynito.ai). **The daily counter looks wrong.** The counter refreshes after each send. Reload if it stays stale. ## Encrypted Sends **"This protected request can no longer continue safely. Restart the whole send to create a fresh reservation."** Use **Restart send**, which replays the whole turn with your prompt and attachments intact. **"Encrypted is not available for the selected model."** The model has no Encrypted route. Pick a row that shows Encrypted. **Web search on an Encrypted chat did not return a result.** The reply says whether it can be retried; retry from the reply rather than re-sending. **Regenerate is disabled on an Encrypted reply.** The previous attempt's outcome is unknown, so a replay could count twice. Send a fresh prompt instead. ## Attachments **"Could not read the selected file. Try another file, or extract the text and paste it."** Try a searchable file or paste the text. **"Could not read the selected file in this browser. Choose Server parsing..."** (Encrypted) Choose **Server** on the chip if you accept that the gateway reads the file before encryption, or paste the text. **"Raw file and image uploads are not supported with Encrypted yet."** Remove the image, use a document that parses to text, or switch to Confidential or Private. **"\[Model] can't read images" or "can't read files."** Pick a model with vision or file support; the alert offers to open the picker filtered to compatible models. **"Uploads must be \[size] or smaller" or "Attachments are too large to send together."** Reduce the file or split the attachments across turns. **"This file type requires Server or Auto attachment parsing."** Legacy XLS and some large PDFs cannot be parsed in the browser. Switch the chip to Server or Auto. ## Balance and Billing **"Repay outstanding billing debt to use this model."** Settle the balance from Billing and the rows unlock. **A notice says the request or the web tools need billing.** Choose a free model, turn off web tools for the request, or add to your balance from Billing. See [Plans](/plans). **A new plan does not show up right after paying.** **Confirming payment** shows for up to a few minutes. Reload if it lingers. ## Storage **"Unable to load your conversations. Your data is safe. Please retry."** Retry; nothing was deleted. **"This browser has encrypted account data from an older storage key."** **Reset local data** starts fresh in this browser. Restore from an encrypted backup afterwards if you have one. **Chats disappear after the browser clears storage.** Turn on **Persist storage** in Settings under Storage, and keep an encrypted backup. See [Backups and Sync](/web-app/backups-and-sync). ## Still Stuck Email [support@trynito.ai](mailto:support@trynito.ai) with the time, the model, and the notice you saw. ## Related Answers grouped by topic.
