Citra does not allow you to write a login when logging into the web service

I have the following problem: if you need to connect to the Internet, where you need to enter a token and login, Citra does not allow you to enter a login, instead it says “Uncpesified”
Please tell me what to do?
I apologize if I wrote incorrectly in English, translated through an online translator*

In order for us to provide better support, we need to see the log generated by citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File

When and where does this error pop-up?
