Most local servers fail DNS check

[Radagast 0]

Hi.

I should have mentioned this sooner, but for some reason on Eddie startup (2.21.8, Win 8.1 x64) most of the nearest-by-ping servers fail the "DNS check" (after the 4th try) except for one, which always connects without problem.

Partly to see if this issue ever resolves, rather than just whitelist this one, I still let it go through them by ping as I want to see if attempts to connect to others might succeed (or at times of high loading on my one, for example). But for months, no, just the one works.

If I go farther afield / out of country servers, they all seem to always work.

Any ideas?

Thanks
