[BUG] IP blocked by TV

[B3rt]

My IP of my server where the API is running on seems to be blocked by the TV (after a restart of my server).
I can connect to the TV using telnet and port but the TV does not respond.

When i try from an other system in the same network the API of the TV works fine, but when run from my server (NAS) it keeps reporting cannot reach API. It can connect to IP and port but the TV part API simply does not respond.

It seems that my TV has a build in firewall which blocks IP, but i cannot find any setting or option to disable or flush it.
A TV system restart had no effect.

From 1 system i get: HTTP request sent, awaiting response... 200 OK
Length: 1107 (1.1K) [application/json]
Saving to: 'system'

Same call from the system which does not work: HTTP request sent, awaiting response... 200 OK
Length: 1107 (1.1K) [application/json]
system: Permission denied

How can i unblock this system?

When i try:
https://192.168.1.140:1926/6/system
via a browser i get a error:
De wachttijd voor de verbinding is verstreken

De server op 192.168.1.140 doet er te lang over om te antwoorden.

When i try:
http://192.168.1.140:1925/6/system
I get a listing.

But when i set the API to use port 1925 and protocol http:// i get an error
Sending POST request to http://192.168.1.140:1925/6/input/key
Request sent!

I have no idea why this is not working, TV seems to block port 1926 randomly, after a while it can suddenly work again, but running API on port 1925 also results in an error...
