How to fix a failed exchange connection

When an exchange key is rejected or won't sync, the message under the card tells you why. Here is what each one means and what to do.

Steps

Open Accounts and read the message under the exchange card. The exchange's own reason is shown in brackets.
“The exchange rejected the key”: copy the API key and the secret again, without extra spaces. Add the passphrase on OKX and Bitget.
Check on the exchange that the key has read permission only. If unsure, create a new key and paste it.
If the exchange asks about IP restriction, turn it off. NovaTrade's server IP can change.
“The exchange refused the connection because of where our servers are”: your key is fine. Contact support with the full message.
“Couldn't sync with the exchange”: click Sync now on the key to retry.
“Your plan's account limit is reached”: delete an account you don't need or upgrade your plan.
If it still fails, write to support with the exchange name and the message you see.

NovaTrade checks the key before saving it, so a key that connects is valid. Syncs run every day, when you open the app and with Sync now.
Several keys of the same exchange can be connected. Each key becomes its own account.
