I noticed that the problem occurs when I deactivate or activate the internet but mostly when I deactivate/activate Rethink Dns, but in both cases it doesn’t always happen.
On Rethink Dns I have the option “block connections that bypass dns” active, could this be one of the causes?
I think this has been happening to me for almost a year, but I thought that sooner or later the error would be solved in some update.
