Troubleshooting
Common problems and what to do.
I keep getting sent to the login page
Only an explicit rejection of your session ends it. If you land on the login page, sign in again; if the app is under maintenance the page stays put and shows a banner instead.
My bot is not trading
- Is it active? New bots are created paused.
- Check Bot Activity: decisions show which condition failed or which veto fired (volatility, low edge, depth, cooldown, dead hours).
- Is the symbol on your blocked list?
- If it uses your own model, check My LLMs — repeated failures pause the bot.
Wallet shows invalid
The key failed validation on Binance. Check permissions, IP restrictions and that testnet keys are used with testnet wallets, then Update keys.
