possible issues with DNS over https

Sorry if this is the wrong place to ask.

Expected Behaviour:

I followed this guide to enable DNS over HTTPS but i’m not sure it’s working correctly. I can now access a bunch of site that I couldn’t before which is good. But when i run this tool i get:

‘?’ for Secure DNS,
‘X’ for DNSSEC (I turned it on in the pihole admin panel),
TLS 1.3 is working
‘X’ for Encripted SNI

Is this expected behaviour? When i run this tool i get no servers found.

Thanks in advance for any advice.
