I had same issue for two days, what worked for me, I downloaded Kiwi browser and logged in through Keychain #feedback

Is it working for you?
Still a question,,, why this error?

Use https://labs.leofinance.io/

If Labs doesn't work, go back to InLeo. I'm accessing it via InLeo, too. Use your Keychain to log into your account.
