Block page not working with latest release

[brokoler]

Hello,

I'm trying to get the DNS block page to work for blocked URLs, at the moment I'm getting an HTTP error when a blocked domain is opened:

I followed following instructions:

• https://www.reddit.com/r/technitium/comments/u4fou4/block_page_app/i52kw6d/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button
• https://github.com/TechnitiumSoftware/DnsServer/issues/459

My configuration:

• Block Page App was installed
• DNS server IP is entered in Settings -> Blocking -> Custom Address
• Default HTTP port 5380 and Default HTTP Port 53443 is configured at Settings -> Web Service
• Enable HTTPS is active in Settings -> Web Service
• Use A Self Signed TLS Certificate When TLS Certificate File Path Is Unspecified is active in Settings -> Web Service
• Ports 80 and 443 are in use by other applications on my server, as I understood 5380 and 53443 should be used when set in the configuration

Troubleshooting steps taken:

Checked if the block page exists in path /etc/dns/apps/Block Page/wwwroot The path exists after installing the app. The redirect to the page is not happening.

Found the issue: Port 80 and Port 443 need to be used exclusively by Technitium for the Block Page to work.
