Description

I'm using NextDNS as a dedicated DNS service, and the configuration is done by installing a configuration profile generated by NextDNS on MacOD device. I've noticed, that when the profile is active, Proxyman can't process any request correctly. This may also be a case for other DNS providers that may use configuration profiles (f.e. AdGuard DNS)

Steps to Reproduce

  1. Generate a MacOS configuration profile on NextDNS
  2. Install generated configuration profile on device
  3. Run proxyman

Current Behavior

All requests return with error code 999 and Internal Error message. When NextDNS profile is removed, everything works without issues

Expected Behavior

Requests are processed normally

Environment

  • App version: 3.15.0
  • macOS version: Ventura 13.1

Hey @ikurek I've downloaded the NextDNS and it seems it isn't compatible with Proxyman. Tried Wireshark / Charles Proxy, and the same issue occurs.

The internal logs show that Proxyman could not resolve the DNS, so the request is a timeout -> 999 Error.

Unfortunately, Google doesn't show any suggestions on how to fix it.

@NghiaTranUIT Thanks for checking my case out so fast! That's a shame this probably can't be fixed. I think it may be a good idea to have a note about this in the docs then 🙂

Sure, I will NextDNS into the Not Compatible List 👍

To make Proxyman and NextDNS work simultaneously, you need to exclude the DNS domain in Proxyman settings.
