I can't authenticate with AlertDragon

This may not be the correct forum for this, but I don’t know where else to get help. I have a funded Tradovate account and I bought the api access. I set up the api key. I’m trying to connect Tradovate to TradingView using AlertDragon, which is supposed to make this easy. I keep getting this error message, which doesn’t give me any clue what’s actually wrong. Does anyone have experience with authenticating AlertDragon to Tradovate through the api?
