Mikrotik web server does not work with Samsung Smart TV

All my clients with Samsung Smart TV can’t navigate… the TV show a connection problem.
If I disable the web server, then all ok.

Even I try use direct access for the sites that samsung use for connection test, but does not work.
Some idea?

Thanks

Post your config.

Export:

/ip firewall nat
add action=redirect chain=dstnat disabled=no dst-port=80 protocol=tcp to-ports=8080

Proxy config, I try everything… access and direct rules, even set memory cache to zero.

/ip proxy
set always-from-cache=no cache-hit-dscp=2 cache-on-disk=no enabled=yes max-cache-size=1400000KiB max-client-connections=5000 max-fresh-time=2d max-server-connections=5000 parent-proxy=0.0.0.0 parent-proxy-port=0 port=8080 serialize-connections=no src-address=0.0.0.0

I try torch to see the traffic, and I saw all ok, even I saw the “ok” response from samsung site, but TV show error. It has no sense…
All clients with samsung tv can’t use it, so I disabled web proxy for now… :frowning:
