Port isn’t just for your grandma anymore. That means it’s time to learn a little more about it, and the first thing to know is how long a bottle of port will stay open, because we all know you. I desactivated my private firewall on windows and my port is still close. I desactivated my antivirus but the port is still closed. I used different port and static address but the port is still closed. I do not know what to do, so please help me. I provide all the screen shots Thanks. The 'Port opened' should say your com port is open. You have to check why is your selected com port open before you open it through Candle. If your com port is opened before you start Candle and it really left open, then no command can be sent to the com port through Candle, that is a normal situation.
Check for open ports and verify port forwarding setup on your router.
What is Port Checker ?
Port Checker is a simple and free online tool for checking open ports on your computer/device, often useful in testing port forwarding settings on a router. For instance, if you're facing connection issues with a program (email, IM client etc) then it may be possible that the port required by the application is getting blocked by your router's firewall or your ISP. In such cases, this tool might help you in diagnosing any problem with firewall setup. You could also find this useful for security purpose, in case you're not sure whether a particular port is open or closed. If you host and play games like Minecraft, use this checker to make sure the server port(25565) is configured properly for port forwarding, then only your friends will be able to connect to your server.

If you're looking for a full list of port numbers check out this wikipedia page. I've listed all the common ports above, feel free to enter any custom port number to check. By default, this site is taking your device's IP address as target ip address (the device through which you're visiting this web page), but you can change the IP input field to check for other IP addresses - remote clients and servers as well. But, please don't misuse this option otherwise, I would have to restrict the IP address to source again (as I had done earlier). Please keep in mind that if you're using a VPN or proxy server then it may not be able to get your device's IP correctly.
Understanding Port Forwarding
![Why Why](/uploads/1/1/8/1/118137138/683267238.jpg)
Port forwarding or port mapping involves translating the address (or port number to a new destination), accepting the packets and forwarding it (using routing table). It's typically used in connecting remote computers to specific programs running on computer (in a private LAN (Local Area Network)). For example : running a public server (HTTP, port 80) on a computer in a private LAN or granting SSH access to a specific computer in a private LAN etc. Read More on Wikipedia.

Port isn’t just for your grandma anymore. That means it’s time to learn a little more about it, and the first thing to know is how long a bottle of port will stay open, because we all know you aren’t finishing a bottle of port in one sitting — or, at least, you shouldn’t be.
For starters, port is a type of fortified wine from the Duoro region of Portugal. It’s got some of the fragility of wine as well as some of the strength of liquor. There are different styles (ruby, vintage, tawny, and white), but in general, it’s between 16 and 20 percent alcohol by volume. Thanks to the fortification, all ports except for vintage will stay good in the fridge for around three months.
In fact, part of the reason port used to be so popular is because of its durability; it would be shipped around the world and it could hold it’s flavor. All wine deteriorates over time after being opened and exposed to oxygen, when it starts to turn to vinegar. You don’t want to drink vinegar. Luckily if you have an open bottle of port, especially young port, the liquid is less susceptible to the damaging effects oxygen and will keep longer than your average bottle of table wine.
Port stays good whether stored in the fridge or at room temperature. If you have space in the fridge, though, put it in there. It will last a bit longer because the cold essentially puts the port into hibernation, slowing the oxidation process.
Opened Port But Still Closed Captioning
Keep in mind that there is one caveat: Vintage port, which is generally more expensive port, loses nuance and character over time and should be drunk relatively quickly. But for your everyday port, put the cap back on it and return to the bottle as many times as you want for three months.
