ANSWERED Eddie Checking DNS failed.

[McLoEa 25]

Hi,
on Fedora 32 and 33 when starting the Eddie client Eddie enters a loop and returns an error message that reads,

Eddie
Checking DNS failed.


If I go to preferences,DNS and uncheck the check AirVPN DNS box then Eddie will start and connect  but I only see my |SP DNS when using dns-oarc dns checker.

I hope someone can help me resolve this as I've not been able to use Edde for over a day now.

Thank you.

I should add that I have re-installed Eddie.

Still not the full picture. Click the lifebelt icon, a window opens. That output, please. It's the support file containing more info on your setup and configuration, highly important stuff when troubleshooting.

Still not the whole picture. The whole picture would've been version info + logs + routes + NIC configuration. Doesn't matter now, because I remember the problem: system-resolved. The easiest way would be to disable it.

@McLoEa

Hello!

We don't know if it was you who pointed the support team to the following article in a ticket:
https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/thread/VPACQVWRG5HCWRPBIOTBAENRT6V6PRA4/

If not, the relevant part is:

Quote

systemd-resolved has been enabled by default in Ubuntu since Ubuntu 16.10, but please note we are doing this differently than Ubuntu has. Ubuntu does not use nss-resolve. Instead, Ubuntu uses the traditional nss-dns provided by glibc upstream, so glibc on Ubuntu continues to read /etc/resolv.conf, as is traditional. This extra step is not useful and not recommended by upstream. We want to follow upstream recommendations in using nss-resolve instead.

systemd-resolved has various operational modes and Eddie, at the moment, can NOT handle properly the "on link" mode bypassing resolv.conf and relying on nss-resolve. In Fedora 33 systemd-resolved is configured by default in a way that Eddie does not handle correctly.

Hummingbird and Bluteit, in the AirVPN Suite, can handle correctly any systemd-resolved operational mode.

Disabling systemd-resolved, anyway, should resolve any issue with Eddie and OpenVPN DNS push. In a few words, the key is going back to handle DNS via resolv.conf file as usual.

If you wish to disable systemd-resolved:

sudo systemctl stop systemd-resolved
sudo systemctl disable systemd-resolved

IMPORTANT: create a new resolvc.conf file and/or restart network-manager service if necessary.

Kind regards
 

[McLoEa 25]

That does indeed appear to have worked,many thanks to all.

I would think it necessary to re-issue those commands after a re-start I will wait and see.

[Staff 10014]

@McLoEa

Good to know, thank you for the info. We are checking how to address the issue with systemd-resolved working in that specific mode.

Kind regards

Thank you! encounter the same problem after reinstalling fedora32 today and lucky to see this post right on top, everything works fine now. Always a thumbs up for the service 
 

[Updater 1]

Same problem here but on a windows7 Os
Have to uncheck the check AirVPN DNS. 
ipconfig/flushdns
Does not help!
Eddie V 2.20.0
