your network have problem …
If you are using “Brave” for a browser, change to another browser. Brave has issues with the microphone (and has had since 2016) with some, but not all apps. Lingq (and Discord) is one of the apps, thus I now us the Microsoft Browser for language learning.
The error looks identical to what you are posting - Network Error
I use Arc Browser will try on other browsers! Thank you
