Failed to complete tunnel connection
The connection to http://cc1e064782fc.ngrok.io was successfully tunneled to your ngrok client, but the client failed to establish a connection to the local address localhost:80.
Make sure that a web service is running on localhost:80 and that it is a valid address.
The error encountered was: dial tcp [::1]:80: connectex: No connection could be made because the target machine actively refused it.
Hi, I was setting up ngrok and got this error, I disabled the firewall too.
Take a look at this video where I show you the error.

Its kind of a message that ngrok successfully created tunnel to your pc at port 80 but there is no service running at that port in your OS, Mostly people run a web server at 80 but you can run any service at that port.
So lets assume you are running a web server in your OS on port 80 then you can access that web server from anywhere on the internet using that ngrok tunnel.

I am trying to troubleshoot connection errors when using SSH tunneling to connect to a rhel 8 EC2 server. Does anyone know of a log location on RHEL 8 that may contain more information when the connection is refused?
For reference I am using the following command (which works on all my other servers)
ssh -i -L 8745:IPOfServer:8443 ec2-user#IPOfServer
I get the error "open failed: connect failded: Connection refused
I can connect on 8080 but 8443 is refused even though the port is open and the application and firewalld are configured to listen on 8443 and 8080.
Thanks!!
I want connect to my other computer with remote desktop connection but i need a problem.
I did setup ngrok and launched it and tried connect it but it doesn't connect.
This is what i did:
Setup and launched ngrok as:
ngrok tcp 5555
and i switched my own laptop and launched remote desktop connection and did that:
But it doesn't connect :(
Note: I allowed Remote Desktop Connection in control panel.
Did i miss something or how to do it correctly?
You have wrong port number for your remote desktop connection. You have to use default RDP port 3389.
Setup and launched ngrok as:
ngrok tcp 3389
Configuration: Server: Ubuntu server 16.04 LTS using webmin
Terminal: Windows 7 Using PgAmin III
I was unable to establish the connection between my terminal and my server through pgAdmin III on port 5432.
On my server I added:
in file postgresql.conf I edited
in #Connection Settings
listen_addresses = '*'
in file pg_hba.conf I added
in #IPv4 local connections
host all all 172.x.x.x/32 md5 //this is IP Terminal (Hidden x)
I checked the port, this is 5432 default and user is postgres
When I try to establish the connection on PgAdmin III:
Host: //My Server IP (Ping console successful)
Port: 5432
username: postgres
password: //My password
Show me the following message:
Server doesn't listen
The server doesn't accept connections: the connection library reports
could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "Mi SERVER IP Hidden" and accepting TCP/IP connections on port 5432?
If you encounter this message, please check if the server you're trying to contact is actually running PostgreSQL on the given port. Test if you have network connectivity from your client to the server host using ping or equivalent tools. Is your network / VPN / SSH tunnel / firewall configured correctly?
For security reasons, PostgreSQL does not listen on all available IP addresses on the server machine initially. In order to access the server over the network, you need to enable listening on the address first.
For PostgreSQL servers starting with version 8.0, this is controlled using the "listen_addresses" parameter in the postgresql.conf file. Here, you can enter a list of IP addresses the server should listen on, or simply use '*' to listen on all available IP addresses. For earlier servers (Version 7.3 or 7.4), you'll need to set the "tcpip_socket" parameter to 'true'.
You can use the postgresql.conf editor that is built into pgAdmin III to edit the postgresql.conf configuration file. After changing this file, you need to restart the server process to make the setting effective.
If you double-checked your configuration but still get this error message, it's still unlikely that you encounter a fatal PostgreSQL misbehaviour. You probably have some low level network connectivity problems (e.g. firewall configuration). Please check this thoroughly before reporting a bug to the PostgreSQL community.
I am trying to add a new server to an existing cluster. I am using community version 2.1.1 on both ubuntu servers on windows azure. I tried to add new server via web interface and via command line. But i am getting following error.
***"Failed to reach erlang port mapper. Timeout connecting to "xx.xx.xx.xx" on port "4369". This could be due to an incorrect host/port combination or a firewall in place between the servers.']***
Port 4369 is open on both servers and iam able to connect to 4369 port on other server using telnet
Got the same error when used the following command.
/opt/couchbase/bin/couchbase-cli server-add --cluster=xx.xx.xx.xx:8091 -u user -p password --server-add=yy.yy.yy.yy:8091 --server-add-username=Administrator --server-add-password=password

What will be the issue? Please help me sort this out.
There are a number of ports required to be open between cluster nodes (in addition to 4369) - I'd suggest ensuring all of the ports listed in the Couchbase Installation Guide - Network ports are open and accessible.
I have SSH access to a web server that is hosting an application on port 8080. I have a SSH session setup and a proxy configured on Chrome to redirect requests to SSH tunnel. I basically configured it using these instructions: http://drewsymo.com/2013/11/ssh-tunnel-in-30-seconds-mac-osx-linux/
I can confirm using Whats My IP that my IP is that of the SSH session and that is working correctly.
But I cannot figure out how to access the local application on the web server that I am SSHed into. When I try localhost:8080 the SSH session gives me an error "channel X: open failed: connect failed: Connection refused"
Any idea what is going on?
You can just create a port-specific tunnel:
ssh -L18080:localhost:8080 username#theothermachine
and then go to localhost:18080 on your local machine. The tunnel will forward your request to port 8080 of the localhost on the other end (and of course, localhost on the other end is the other machine itself). If that doesn't work for some reason, then replace localhost by 127.0.0.1 in the ssh command.
