1. The problem I’m having:
I’m trying to run a reverse proxy thru DuckDNS to have my Jellyfin server remotely accessible.
I have downloaded Caddy and made a Caddyfile, and ran Caddy thru the Windows Powershell, as well as thru a .bat file but keep getting the error message “An attempt was made to access a socket in a way forbidden by its access permissions.”
Ports 443 and 80 are allowed in Windows Firewall and Port-Forwarded on my router.

Error: loading initial config: loading new config: http app module: start: listening on :443: listen tcp :443: bind: An attempt was made to access a socket in a way forbidden by its access permissions.
This will sometimes change from port TCP:443 to TCP:80.
3. Caddy version:
v2.8.4
4. How I installed and ran Caddy:
From Releases · caddyserver/caddy · GitHub, selected the caddy_2.8.4_windows_amd64.zip release, extracted the .ZIP file to desktop, made the Caddyfile, and ran Caddy from Powershell.
PS C:\Users\Administrator> cd C:\Users\Administrator\Desktop\caddy\
PS C:\Users\Administrator\Desktop\caddy> .\caddy run
I even tried making a .bat an running from there.
cd C:\Users\Administrator\Desktop\caddy
caddy run
pause
a. System environment:
Microsoft Windows Server 2022
Version 21H2 (OS Build 20348.2527)
x64 bit
b. Command:
Powershell
PS C:\Users\Administrator> cd C:\Users\Administrator\Desktop\caddy\
PS C:\Users\Administrator\Desktop\caddy> .\caddy run
.bat File
cd C:\Users\Administrator\Desktop\caddy
caddy run
pause
c. Service/unit/compose file:
N/A
d. My complete Caddy config:
jellyfin.lunmar.duckdns.org {
reverse_proxy localhost:8096
}
I have also tried adding
{
auto_https disable_redirects
}
from a Reddit search for the solution to the top of the Caddyfile which doesn’t work.
