Insomnia 2021.2.0 doesn't use local dns server

[xwillq]

Describe the bug
Latest version of insomnia doesn't use local dns server if there are any other options

To Reproduce
Steps to reproduce the behavior:

1. Configure local dns server
2. Configure local dns server as preferred and some other server as alternative (for example 1.1.1.1)
3. Make a request to the domain which should be resolved with local dns server
4. See Error: Couldn't resolve host name
5. If you capture traffic with wireshark or check logs of local dns server, you can see that it didn't receive any queries

Expected behavior
Insomnia uses local dns server for dns lookups

Desktop:

• Installation Method: Installer from github releases
• App Version: 2021.2.0

Additional context
If you remove all dns servers except the localhost, then insomnia will use localhost.

The same problem after upgrade to 2021.2.0 today.

Hi @xwillq,

Thank you for reporting this! We have confirmed the issue, and believe it's likely due to our recent upgrade of the node-libcurl dependency for the 2021.2.0 release, which changed what DNS resolver backend is being used.

We are looking into ways to address it, and hope to get it fixed as soon as possible.

Is there a workaround for the time being? Or a way to downgrade?

Update: we have identified that it is indeed a regression from the update to node-libcurl that impacts all platforms and we are working with the maintainer to get a build out sometime tonight or tomorrow morning that doesn't use c-ares for DNS to fix the issue.

In the meantime we have pulled 2021.2 from the auto-update api to reduce the impact on users, for those who are impacted please download the previous release mentioned here.

Update: new build for node-libcurl is up, we are preparing a new patch release for Insomnia which is going into testing and will be released shortly. Thank you to everyone who was a part of making this happen. ❤️

Test build can be found here.
