I got the following error while running curl:
curl: (7) Failed to connect to 127.0.0.1 port 8080: Connection
refused.
It seems that it is easy to debug, but, I didnt find how to solve it.
The adress 127.0.0.1 is mentioned in the file etc/hosts.
I am using curl version 7.47 on Ubuntu system.
Anyone has an idea about it ?
Thank you.
Make sure you have a service started and listening on the port.
netstat -ln | grep 8080
and
sudo netstat -tulpn
Try curl -v http://localhost:8080/ instead of 127.0.0.1
Listen to the port in one session and then open another session to test it with l$ curl -v http://localhost:8080/
It should work. That's how I worked although in l
Termux
You have to start the server first, before using curl. On 8/10 occasions that error message arises from not starting the server initially.
127.0.0.1 restricts access on every interface on port 8000 except development computer. change it to 0.0.0.0:8000 this will allow connection from curl.

I got 3 curl calls in my laravel code
$fullNode = new \IEXBase\TronAPI\Provider\HttpProvider('http://127.0.0.1:8090');
$solidityNode = new \IEXBase\TronAPI\Provider\HttpProvider('http://127.0.0.1:8091');
$client = new \EOSPHP\EOSClient('http://127.0.0.1:8888');
$fullNode and $solidityNode work without any problem.
$client gets the following error message:
cURL error 7: Failed to connect to 127.0.0.1 port 8888: Connection refused (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)
I checked this on my nginx machine:
sudo netstat -tulpn | grep LISTEN
The result did show 8090 and 8091 but not 8888.
I guess there is a problem with the port, it might not open? I'm not that experienced in working with ports, may someone can tell me where to go from here and if/ where i open the port for LISTEN to CURL? As said, this is a nginx linux machine.
I have installed Apache Superset on a remote Linux Server and initialized it on port 8080. When I pull up localhost:8080 on the Linux server, the homepage shows up which suggests that the installation worked as per their instructions here.
When I try to access this page from my laptop (Windows- Browser:Chrome) with http://server-name:8080. It gives me the 'This site can't be reached' page.
I tested using netcat if the connection was open by typing nc -zvw3 server-name 8080 and it gave me Connection to server-name 8080 port [tcp/webcache] succeeded!
I have Jupyter installed on the same server on port 8888 and it works perfectly. Any thoughts would be greatly appreciated.
You may need to try this command by defining the IP address:
superset run -h 0.0.0.0 -p 8080
This question shows research effort; it is useful and clear
I have checked the cURL not working properly
When I run the command curl -I https://www.example.com/sitemap.xml
curl: (7) Failed to connect
Failed to connect on all port
this error only on one domain, all other domain working fine, curl: (7) Failed to connect to port 80, and 443
Thanks...
First Check your /etc/hosts file entries, may be the URL which You're requesting, is pointing to your localhost.
If the URL is not listed in your /etc/hosts file, then try to execute following command to understand the flow of Curl Execution for the particular URL:
curl --ipv4 -v "https://example.com/";
After many search, I found that Hosts settings not correct
Then I check nano /etc/hosts
The Domain point to wrong IP in hosts file
I change the wrong IP and its working Fine
This is new error Related to curl: (7) Failed to connect
curl: (7) Failed to connect
The above error message means that your web-server (at least the one specified with curl) is not running at all — no web-server is running on the specified port and the specified (or implied) port. (So, XML doesn't have anything to do with that.)
you can download the key with browser
then open terminal in downloads
then type sudo apt-key add <key_name>.asc
Mine is Red Hat Enterprise(RHEL) Virtual Machine and I was getting something like the following.
Error "curl: (7) Failed to connect to localhost port 80: Connection refused"
I stopped the firewall by running the following commands and it started working.
sudo systemctl stop firewalld
sudo systemctl disable firewalld
If the curl is to the outside world, like:
curl www.google.com
I have to restart my cntlm service:
systemctl restart cntlm
If it's within my network:
curl inside.server.local
Then a docker network is overlapping something with my CNTLM proxy, and I just remove all docker networks to fix it - you can also just remove the last network you just created, but I'm lazy.
docker network rm $(docker network ls -q)
And then I can work again.
When i run the jboss-cli.sh,
I get this message.
[root bin]# sh jboss-cli.sh
You are disconnected at the moment. Type 'connect' to connect to the server or 'help' for the list of supported commands.
[disconnected /] connect localhost
The controller is not available at localhost:9999
[disconnected /] connect
The controller is not available at localhost:9999
[disconnected /] connect localhost:9999
The controller is not available at localhost:9999
[disconnected /]
Also i have another installation of jboss5 GA. I hope that is not interfering.
Although that is totally shut down for now.
Native management interface is :9999 in standalone.sh
Please throw light on this issue.
#
EDITED

When i stop my service with "service jboss stop"
i get this message
[root# bin]# *** JBossAS process (7302) received KILL signal ***
grep: /var/run/jboss-as/jboss-as-standalone.pid: No such file or directory
I Dont know how to check whether server is listening on the port 9999 or not.
Few more details
[root bin]# netstat -anp |grep 9999
tcp 0 0 127.0.0.1:9999 0.0.0.0:* LISTEN 7931/java
[root bin]# netstat -anp |grep 8080
tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN 7931/java
JBoss processs id and the server id acquiring these ports is same.
This question has two issues ,
First, i have provided debuging parameter in the startup script.
If you see 8787 that means you have somewhere provided debuging argument.
Second and the most important one controller not available #localhost or #IPADDRESS .
Please check if you have used port offset, as it increments all the ports by the number with with you have set port offset.
Suppose port offset is 2
Then try to access connect localhost:10001 Port i.e 9999+2
On my production server sometimes it does not works with localhost , but works with IP address.
Then try to access connect IPADDRESS:9999
OR
Then try to access connect 127.0.0.1:9999
Please check in the firewall weather the port 9999 or what ever with port offset, if the port is not open in the firewall it gives error,
I asked this question 6 months back and the above checks has solved
the problem always.
This is probaby because you have changed your binding configuration and jboss does not bind to 127.0.0.1.
In case your jboss instance is not binding to 127.0.0.1, you may use --controller option as follows:
./jboss-cli.sh --controller=YOUR_IP:9999
Use netstat -anp |grep 9999 to find out if port 9999 is in use and by which process id. You could also check the host.xml used by the controller to configure the proper native port.
In the host xml, you should find the default port:
<native-interface security-realm="ManagementRealm">
<socket interface="management" port="${jboss.management.native.port:9999}"/>
./jboss-cli.sh --controller=localhost:9999 --connect
You open the debug-port with jboss-cli.sh. Either you activated in jboss-cli.sh:
# Sample JPDA settings for remote socket debugging
# JAVA_OPTS="$JAVA_OPTS -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"
or you set JAVA_OPTS with such an option in you environment. See
echo $JAVA_OPTS
I guess you did this for two jboss-processes, and you get a port-conflict. See
netstat -nap | grep 8787
I recently faced this issue and the root cause that I found was completely different than it is listed above. It is because for some other project I shifted to JDK 1.8 from 1.7. Boom! and error started coming up...I took hell lot of time figuring out why it is coming up before finally realizing I changed my JDK version.
It might be because JBOSS 7 doesn't work with 1.8 of which I have limited knowledge but yes this might prove useful for some cases.
According the the Charles Proxy configuration page, you can manually set up a proxy if you use your localhost with port 8080.
The syntax is curl --proxy localhost:8080 http://google.com/
However, this is not working for me. Here is my syntax and results - i'm also using the -v option for debugging:
curl -v --proxy localhost:8080 http://google.com/
* About to connect() to proxy localhost port 8080 (#0)
* Trying 127.0.0.1... Connection refused
* Trying ::1... Connection refused
* Trying fe80::1... Connection refused
* couldn't connect to host
* Closing connection #0
curl: (7) couldn't connect to host
I can connect to localhost:8080 in the web browser, and the results are logged in the proxy. However this is not working, the connecting is refused and nothing is logged.
So far I have also tried:
- executing this as root
- using 127.0.0.1 instead of localhost
- using wget instead of curl
- disabling the system firewall
What am I doing wrong? What else can I try?
I had some success using port 8888:
curl http://www.google.com --proxy 127.0.0.1:8888
Connection refused would suggest that nothing is listening on port 8080. Charles has to be running (and listening on port 8080) for curl to be able to use it as a proxy. That or you've got a firewall actively blocking that port, preventing anything from connecting.
