Hello,greetings

How do I create it, I’m running on windows 10 and I couldn’t find any sources on how to do it on Windows 10.
The application OpenSSL will only run on computer from Win XP x64 to Win 7 x64 bit OS running machines.
I have successfully started and connected my phone and hardware to the server, how do I change the domain address and make the website secure. I entered what my domian name needs to be on the line as server.host=smome.com , I changed the line on contact.email as contact.emal=MyEmailId , I enabled allow less secure apps setting and i started the server and the server doesn’t give the output as

Have you opened port 80 on your router/firewall? And redirected to your server pc? I noticed that lets encrypt stopped working when I closed it so I reopened it.

that port on my computer is open and my pc’s firewall is permanently diabled

#hardware mqtt port
hardware.mqtt.port=8440

#hardware ssl port
hardware.ssl.port=8441

#hardware plain tcp/ip port
hardware.default.port=8442

#http, plain web sockets and plain hardware port
http.port=80

#secured https, web sockets and app port
https.port=9443

this is a pat ofmy server.properties code, did I make any mistakes ? please let me know.

Doubt your errors are there

I port checked your dns Adress “smome.com”
80 is open
443 is closed (default https port)
9443 is closed as well.

This leads me to believe that you have not configured your routers firewall and that could be the culprit

Make sure to use a static ip for your server pc and open and redirect

Port 80 to pc ip through port 80
Port 443 to pc ip through port 9443

This is my router portforward settings
My server pc has a static adress of 192.168.1.3

It’s not a DNS or FTP server those are other types. I do not know what category blynk server falls under.
It runs on java and uses a custom TCP/IP protocol.

Static IP you must(preferably) set in your router, As I do not know how it looks on your specific router I can’t help you right now. You need the MAC adress of your server PC aswell for the “identification”. Poke around your routers DCHP settings.
edit:
Static IP is a user choice, you can use the current one by opening command prompt and writing ipconfig /all
look for physical adress, that is your MAC
look for IPv4 address, that is your server pcs current local address

Your settings are wrong. Please try these and avoid misstyping, its port 443 not 433.

Ugh my bad. I missed that in your server properties you use

#http, plain web sockets and plain hardware port
http.port=80

Do only one of these changes

  1. Change server.properties http port to 8080

OR

  1. Change router portforward of port 80 to 192.168.1.7 on port 80 instead of port 8080

Made the change to the server.properties but I get an error as

sorry for my inconvenience

I wonder if it has something to do with your port 443 reporting as closed
image

Because when I try my IP 443 is open. Maybe you could try rebooting your router. That might change your pc IP though.

14

can I open the port in anyway ?

15

That is what you did when you port forwarded. You opened a port.
Does not seem to have taken or your PC is blocking 443

16

then what should i do just restart the router ?

17

Try it. If everything is “unblocked” and it still is not working then I’m out of ideas.

18

If 443 is blocked or somthing, cani assign another port ?

19

It is something localy on your network or PC that is blocking port 443. There is no need to change it as it will likely move the issue to another port.

What is the brand and model of your router?
