How can this issue be reproduced?

  1. Brave Nightly just stops connecting to anything after working for an hour or so without any problem.
  2. Works again after just re-booting the browser.
  3. Can’t even access Settings to delete cookies unless I load the standard Brave browser to do that.

Expected result:
Just should keep working.

Thanks.
