I try to connect my flutter app at the Django API that are being used as a backend. I run the app on my localhost while I am connected to my home wifi and everything works fine.
When I try to switch the connection to another wireless connection, I get Exception has occurred.
_ClientSocketException (Connection timed out). I have to mention that I've already changed the IP address with the new ipv4 from command prompt after switching the network. I tried everything I found on stackoverflow but no success.

I have this server, client code in which we run the server as a subprocess in py.test and create a client object and connect it with client.
But I am getting the Connection Refused error, when I am tracing it to open() function wherein the socket is trying to connect to ip and port.
There a comment is mentioned that For Connection refused errors, work around startup races.
What are the different ways, I can fix the startup race issue?
I had a postgreSQL server/database working in a local area network in Windows. To have access to it through Ethernet I changed the IP in the router settings. Everything was fine. But when I came today to the office, I could not have connected to the server. Moreover, I cannot even create a localhost server on that PC. The error is "Unable to connect to server:" and nothing else. When I turn off the postgres in services it specifies the error with TCP/IP, port, etc. But not when the service is on. When connecting to the server, the pgAdmin asks for the postgres password. Endlessly, thou the password is printed correctly and the METHOD is set to trust. The reinstallation did not help.
What does this error mean? And what is the cure?
I set up a Postgres server on my computer (windows) at home just to run some basic work when I am away from home, but I am unable to connect to it outside of my home network. I have setup my pg_hba.conf file to accept connections from my laptop and I have set listen_addresses to '*'. It works perfectly fine if my laptop is on the same network as my home computer, but if I go to any other network it fails to even recognize the connection.
Returns the following in pgAdmin4: could not connect to server: Connection timed out.
Any ideas?
I am running a Postgresql server hosted on heroku as part of an app I am developing. I've been using PGAdmin as a frontend to set up my tables and also check to make sure the app is correctly writing data to the tables. When I am at home it connects fine and I can use it with no problems. It also works when I tether to my phone's WiFi hotspot. However when I am in university on the WiFi it does not connect. I get the following error:
"could not connect to server: Connection timed out (0x0000274C/10060) Is the server
running on host <MY HOSTNAME> and accepting TCP/IP connections on port 5432?"
I'm trying to troubleshoot this. I tried the obvious things like checking my hostname and port are correct (they are, because it works from home!) and checking that Pgadmin has permissions in windows firewall (it does). Not sure what to try next.
Is it likely to be that the port is blocked? I used an online port checker which reported that the port (5432) was closed, however it also says this when using my phone's wifi hotspot (which normally works, as I said). Is there another port I can use with Postgresql?
OK, it turns out the port 5432 was actually closed on my university's WiFi. I was able to request that it be opened, and everything is now working.
trying to upload file using apache file upload, but getting this error:
java.net.ConnectException: Connection refused: connect
it was working yesterday, but today it is not working
Either the firewall configuration (by which I mean port forwarding, not access rules) has changed or the server process isn't running.
If this is a locally hosted server. make sure the correct port is forwarded for the correct IPV4, they change often and without much reason.
