Not that I can think of - there’s no anti-virus or MDM on the devices.
The majority of websites work, but there’s two distinct symptoms:
- Microsoft Teams and Spotify simply refuse to load, citing network errors.
- It’s pretty often that the first load of a page will fail and it requires a reload.
#2 was something that I thought was just a cursed device but it seems like others have encountered the same.
On WARP 2022.2.288
, there are no issues (that I can spot).
Upgrading to WARP 2022.5.346
and I can reliably reproduce #2 just by browsing through a few websites - there is no error, just a simple “unable to connect” from Firefox.

On the off chance it was a Firefox specific issue, it is reproducible in other browsers.
However in Chrome, I can refresh here all day long and it’ll never get anywhere - citing --> net_error = -105 (ERR_NAME_NOT_RESOLVED)

Trying to launch Microsoft Teams fills the Teams logs with similar net::ERR_NAME_NOT_RESOLVED
errors.

There is slight differences in how the local DNS proxy & 1.1.1.1 return a lookup for the one of the URL’s it is having issues with, teams.microsoft.com
errorCode: -105, errorUrl: https://teams.microsoft.com, message: ERR_NAME_NOT_RESOLVED

Albeit both end up returning the same IP
Spotify’s logs don’t give much information beyond http_error_fail
but it is reproducible going to and from 2022.2
and 2022.5
The ID I received was 507979
- thanks for the help!
