5. What I already tried:
i tried to change my Caddyfile config like this
:80 {
reverse_proxy localhost:8080
}
it worked well, but when I tried to use my subdomain, it was not working, and got the error like this “The page isn’t redirecting properly” , why do I want to use my subdomain? because I want to use multi ports for this case for the next steps after I resolved this.
