Hi!
I use Dnscrypt proxy, but the server error is only for Cloudflare.
Continuous error: [2018-09-26 17:28:50] [INFO] Server [Cloudflare] returned temporary error code [2] - Upstream server may be experiencing connectivity issues.
1 hour min. I get 100 error messages.
I actually receive an error message every time I download.
So it is much slower than any isp or dns provider (google, opendns…)
My lan seed test and ping test suitable!
No lost package:
Sorry Google Translate!
Can you share which domain name is returning SERVFAIL? I don’t see any failures for www.idstudio.tk
I do not know what doman is causing trouble, and I get the error messages with continuous use.
I do not think there is a domain name problem, it is transfer, the connection is the problem.
I’ve been researching the quality of connection since last night (ping - Peak Hour 1.0.0.1).
And since then I did not get an error message.

Hopss:)
I opened my gmail in my browser and I got more error messages right away.
But the gmail work!
