DNS over HTTPS does not work when applied through GPO

Hello team,

We've deployed a GPO to change Firefox setup to use our DNS over HTTPS with a custom Cloudflare URL.

The registry settings are: HKLM\Software\Policies\Mozilla\Firefox\DNSOverHTTPS\Enabled = 0x1 HKLM\Software\Policies\Mozilla\Firefox\DNSOverHTTPS\ProviderURL = "https://modifiedentry.cloudflare-gateway.com/dns-query" HKLM\Software\Policies\Mozilla\Firefox\DNSOverHTTPS\Locked = 0x1

When looking into Firefox policies it seems to be applied correctly: about:policies Active Policy Name Policy Value DNSOverHTTPS Locked true ProviderURL "https://modifiedentry.cloudflare-gateway.com/dns-query"

This doesn't work, but manual setup from Firefox Settings using the same URL does.

Any clue why this could be failing?

Thanks in advance

Ok... Windows team made a typo in the GPO. Enabled had a space in the end. Solved.
