HI Guys i have had my reverse proxy for year with no issue. I even have wild card DNS setup which worked fine but after some tinkering to tighten security it broke everything. I have spent 48 hrs to try and get back to it working s i reset it to my old settings but the whole of my domain is still blocked. Please can you review why CF is blocking all the domain & subdomain request try https://radarr.daddycloud.co.uk/
Keep getting 401 Authorization for every one of the subdomains, but this has worked for years on my original setup which i have reset!!!
Any further details or images required please ask
