@TheoGBXuber I wound run the k2 setup again and make sure k2 is configured to use/host on port 5555 (default) and you did not change the port number. 

Then you can run the following from a PowerShell prompt on that K2 server to validate connectivity: Test-NetConnection IP.XXX.XXX -Port PortNumber

Note: K2 Dev license requires to run K2 server on Console all the time.

Thanks Rusty,

I definitely didn’t change the port number (this is already my third time going through the installation). I have tested as you say but nothing is found there which leads me to think there’s something else the installer should be running or something it can’t run.

The errors I’m seeing are in the HostServer log files. I note (strangely) that K2 seems to be using two different usernames for me. My work is not setup on a standard AD system any more. I am on a domain that but there is no direct controller linked. I see this in the errors:

64005 Failed to resolve '{MyMachineName}{myusername}': Failed to translate name: {MyMachineName}{myusername}."

So it’s as if it thinks I should have a user of the type DOMAINusername and one of MACHINENAMEusername.

@TheoGBXuber Usually after loading the k2 licenses, k2 will load authentication providers. Is K2 configured to use Windows Active Directory or something else as authencation provider? What does your �K2].]HostServer].]SecurityLabel] table looks like?

Like you said, if you’ve configured k2 to use AD and it cannot contact the AD controller than it will fail to authenticate.

It’s upgrading from a 4.7 installation that was supposed to be setup to use local SQL authentication. Good point, I’m going to just make a fresh 4.7 install and make sure that was the case to see if it resolves it.

Thanks

Okay, uninstalled everything and tried the 5.3 from scratch. I’m no longer seeing any references to two different users and this time I was definite that it’s not using AD but sadly the 5560 port request is still failing over and over for the K2HostServer.exe

Just getting this repeated over and over

@TheoGBXuber Before installing fresh K2 5.3, did you delete the k2 database and k2 artifacts from the file storage?

The error message “SourceCode.Hosting.Server.Runtime.HostLoadBalancedServerManager.Poll”, did you install Network Load Balancer feature on the server?

Hi TheoGBXuber,

Do you have a load balance ? Kindly check if you are able to connect to that server or if it is running.

The below information can be seen from the error message that you have posted 

Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it {localhost ipv6}]:5560

Cheers,

Kate

Yeah I did a completely clean installation in the end - deleted everything from IIS and SQL Server and nuked any leftover directories in Program Files (x86)

Thanks Kate but this is a purely local Windows 10 Enterprise machine installation, so no load balancer. I will try going back to my IT department to see if they can open this port in my local firewall but it’s strange I never had this with 4.7. That’s why I’m wondering what port 5560 is used for.

Thanks

Theo

@TheoGBXuber I have never install k2 server on windows 10 so I would not advise it, highly suggest to install k2 server on Windows Server.

I don’t have the option of Windows Server OS for my development machine really. Not sure all the other software I need would work on it and our IT system doesn’t cover that. It needs to be installed for the Visual Studio integration stuff.

Maybe I’ll see if I can just install that on its own and get it to work.
