Currently hosting a microsoft azure server that has a SCP: Secret laboratory game server on it.
OS: Ubuntu 20.04
After setting up the server and downloading the server files, I can't seem to connect to the server. The port that is needed for the game server is 7777 and I have the port open under NSG with UDP and TCP protocol, but after using multiple port checkers and trying to connect in game, I always got the port closed answer or was given a connection error.
I have tried using the azure's own troubleshooter, but that says the ports are open. Tried different ports like 7778 or 7779. Checked the firewall, but I dont even have it enabled.

I am trying to connect to VS2019 remote debugger installed on virtual machine (Windows Server 2022 version 21H2) hosted in Azure cloud.
Remote debugger is installed correctly and I've checked that TCP port number in options is set to 4024.
Now, when I try to connect from my machine I got an error message
Unable to connect to 'hostname'. The Visual Studio 2019 Remote Debugger (MSVSMON.EXE) does not appear to be running on the remote computer. This may be because a firewall is preventing communication to the remote computer. Please see Help for assistance on configuring remote debugging.
So the first thing we tried was properly set up firewall and open needed ports. After that it still doesn't work.
I've checked which ports msvsmon.exe process listens on and found out it does not use the preferred port 4024 but rather it listens on some random ports.
netstat -abo -p tcp
TCP 0.0.0.0:20031 hostname:0 LISTENING 9920
[msvsmon.exe]
TCP 0.0.0.0:20035 hostname:0 LISTENING 11148
[msvsmon.exe]
Even when remote debugger window falsely states
1.9.2022 14:25:26 Msvsmon started a new server named 'hostname:4024'. Waiting for new connections.
I've also tried starting msvsmon.exe with /port option. GUI says it used this port but in fact it still listens on some random port.
Any idea, why msvsmon starts server on random port instead of the one set in options?
Things I did so far.
my website is running on port 80.
had opened my port 80 with the help of VPN book. confirmed with canyouseeme.org.
Created an account in noip.com. Created a hostname.
using the AsusZenfone3 mobile phone and airtel 4g mobile data. getting internet to my laptop via Hotspot/Tethering using wifi from phone and laptop.
had downloaded DUC from noip and it is running fine.
had configured a device in noip.com for my host like below,
- hostname
router brand as Asus(I don't use any router/ I don't know what router is used)
-software/device as HTTP
Is there any computer running on your network? Yes
downloaded Duc
port 80 check success
my host has been successfully configured.
I also added rules to my firewall to enable TCP and UDP 80 port access.
But still, I am not able to access my website.
I tried calling my website from the proxy server, I get an empty result from the server.
Cannot say for certain, but it sounds like you opened port 80 on your router but likely did not forward that port to an address on your local LAN.
Somewhere in your router config you should be able to find a port forward option. So any traffic received on that port would need to be forwarded to the local IP of the computer running the webserver.
Problem
Your port is not forwarded through your gateway connection.
Solution

I tried to look for solutions and most of them talk about adding HTTP, RDP, HTTPS to security group which I have already done. I have a basic hello world nodeJS application running on Amazon Windows Server 2012. I want to access this application using DNS but it's showing ERR_CONNECTION_TIMED_OUT in my local laptop browser.
Configuration:
I have RDP, HTTPS, HTTP, SSH, Custom TCP Protocol with 9000 port (nodeJS is running on port 9000) for inbound rules and for outbound default "All traffic" rule is present. I have not done any changes in the Windows Server 2012 configuration. WHen I run localhost:9000 in the windows server 2012 then server returns "Hello World" but when I try that on my local machine with DNS : 9000 then it says ERR_CONNECTION_TIMED_OUT
Thanks for everyone's support. Special thanks to Viccari. His suggestion (in the comments below the question) worked. I needed to add the port to the firewall. So basically after adding all the protocols to the security group, I had to add the new port on which the NodeJS is working, to the firewall in the server. Finally its working.
I got a problem with Azure Endpoint using Ubuntu.
SYMPTOMS
Online port scanner reported that port 1194 is closed even though the End point was defined to be open at Azure Web Interface for that VM
SETTINGS:
UFW, aka Ubuntu Firewall is inactive.
No IP Table was defined in Ubuntu
On Azure web management interface, endpoint called VPN, port TCP 443 and UDP
1194 was set to open, bidirectional allowing direct return. Public and Private port is both 1194, and both 443
lfor and netstat on ubuntu reported thata service is listening on 1194, got NC to listen to 443
DIAGNOSIS
From Ubuntu, I can see the internet. Pinging Google, getting updates works fine.
I can remote into the machine using default port 22, which is a default open endpoint defined by Azure Ubuntu Image
Restarted Ubuntu everytime a setting change.
Tried deleting and re-creating Endpoint rule, failed
Tried shutting down the VM, and delete and recreate endpoint rule, failed
I CAN Telnet to my local host from Ubuntu via 443.
TROUBLESHOOTING STEPS DEFINED
From my local computer, unable to telnet to the Ubuntu server via 443. Ok on 22, terminated because of protocol mismatch, but that is of course fine.
Online port scanners all report that 1194 was closed and so is 443
Some help would be appreciated.
I think that you need to manually configure the endpoint.
Please check https://azure.microsoft.com/en-us/documentation/articles/virtual-machines-set-up-endpoints/?rnd=1 for more information.
I hosting a dedicated Server(win2008 Standart). IIS is installed. There are several Websites bound to different ports(eg SharepointServicesCentralAdministration to 17012).
Every website work well if is bound to port 80 but if i change the port i get timeout (connection via internet) - local it works well.
(Hardware and software firewall are down.)
For some additional test a c# TcpClient Instance is listening on port 12345. If i try connect via internet i get exception:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond xxx.xxx.xxx.xxx:12345 - seems the same issue...
Any idea what could be wrong?
You most likely have port 80 forwarded to your machine from your internet bordering router/firewall.
You would need to have the other ports forwarded as well in your router/firewall for these other ports to work.
This also assumes you already opened the local firewall ports as you mentioned above, which is also required!
Is it possible for other computers in the local subnet to connect? Probably only the local subnet is allowed. The setting needed for ip-restrictions has to be installed: http://www.hrzdata.com/node/46
