I just got the latest IdentityServer4 and quickstart code and trying to follow the instruction of quickstart to set it up and test. And I am using VS.Net 2019 on my Windows 10 laptop. The setup process seemed to be fine and the code compiled with no issues. But when I run the Client project from VS, I got the error message "Error connecting to https://localhost:5001/.well-known/openid-configuration. No connection could be made because the target machine actively refused it.." at the following line of Client code:
var disco = await client.GetDiscoveryDocumentAsync("https://localhost:5001");
Can someone tell me what I might be missing here? By the way, localhost:5001 should be my identity server and I use https://localhost:6001 for my API.
Per our discussion in the comments, a good first step is to run a telnet test:
telnet localhost 5001
The failed connection showed us that either your server was not running or it was listening on a different port. Ultimately you were able to determine that it was not running, and you concluded that it did not start due to an issue with your IIS Express profile.
I'm getting SQL error 40 when I try to connect to remote SQL using SQL management studio from my local system. It connects without any error when I switch my wifi to another network but it shows SQL error 40 from my office internet connection. I used to connect earlier from the office too. I've checked multiple networks and it throws the same connection error 40 on some other internet connections too. I've tried using the IP address instead of domain name on those networks but no luck. I've also checked the port on firewall, TCP IP, Named pipes everything is up to the mark. Any help would be highly appreciated.
Error on some internet connection:
Connects fine from other internet connection:
This sounds like a routing or Firewall issue on the troublesome network. It may possibly something to do with a dynamic IP address if it worked earlier on that network.
You need to speak to whoever manages the network on which you are getting the error and ask them to investigate.
I am pretty new to postgreSQL. I am running version 9.5 of it on my main machine. I am trying to establish a telnet connection from my virtual machine. Before doing that I have configured the postgresql.conf and pg_hba.conf files to accept connection from remote machine in the same network.
However when I start the postgresql service using:
service postgresql start
The process show the status:
active(exited)
and the telnet connection is also refused(when i run telnet x.x.x.x 5432). Also when i start the postgresql service using
systemctl start postgresql#9.5-main
the status is active(running) but the telnet connection is still refused. Can anyone tell me how to establish the telnet connection? I dont really know whats going on and I am new here so please dont mind if its a noob question
I'm trying to create a database in Intellij using Apache Derby. I have everything configured, but when I try to create the database, an error message appears:
Connection to ejercicio#localhost failed.
[08001][40000] java.net.ConnectException: Error on connecting to localhost server in port 1.527 with the message Connection refused: connect.
I have tried everything (executing startNetworkServer, writing create=true at database title) and it still doesn't connect.
Could anyone help me? Thank you.
This is really make me crazy. I try to do this since last month but until now I still cannot do any connection between SQL Server 2000 to Pentaho User Console. Before this I got error in connection because it cannot found port 1433. But now after I make sure that port is enable, I got this error.
Why this error occur? What step I need to take to solve this error?
