Unable to get DOH to work

[xd003]

I have deployed adguard home on linux docker using the following docker compose

  adguardhome:
    image: adguard/adguardhome 
    container_name: adguardhome
    restart: unless-stopped
    ports:
      - "53:53"
      - "853:853"
    expose:
      - "80"
      - "443"
      - "3000"
    volumes:
      - /home/ubuntu/docker/adguard/data:/opt/adguardhome/work
      - /home/ubuntu/docker/adguard/config:/opt/adguardhome/conf

I intend to have both DOT and DOH working. Accordingly, i have enabled encryption in settings, created persistent clients and added their ClientIDs to Allowed Client list. SSL certs and everything is perfect.
I am using reverse proxy through nginx proxy manager to access the web interface. It is reverse proxying http://adguardhome:80 to *.domain.subdomain.site & domain.subdomain.site

DOT is working perfectly through the endpoint - clientid.domain.subdomain.site but i am unable to access DOH through https://clientid.domain.subdomain.site/dns-query

Thanks to Andrey Meshkov for the help on telegram.
Setting allow_unencrypted_doh to true in the Adguard Home configuration file has fixed the issue
