Sign-In and Sessions
“Your session expired. 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. 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. 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.Still Stuck
Email support@trynito.ai with the time, the model, and the notice you saw.Related
