Cannot assign requested address

EventStoreDB
1

Good day and nice to meet you,

i am just introducing eventstore and for presentation purpose i wanted to setup a secured single node instance in the internet. I am using a ubuntu virtual machine hosted in the azure network. So i followed the instructions on the documentation to setup eventsource on an linux host, but unfortunably i cannot access the web frontend (for TCP connections i have not tried out yet).

I am getting the following error:

Unable to start Kestrel. Fatal i:4234826381 System.Threading.Tasks.TaskCanceledException: A task was canceled.\n at Microsoft.AspNetCore.Server.Kestrel.Core.KestrelServerImpl.BindAsync(CancellationToken cancellationToken)\n at Microsoft.AspNetCore.Server.Kestrel.Core.KestrelServerImpl.StartAsync[TContext](IHttpApplication`1 application, CancellationToken cancellationToken)\n at Microsoft.AspNetCore.Hosting.GenericWebHostService.StartAsync(CancellationToken cancellationToken)\n at Microsoft.Extensions.Hosting.Internal.Host.StartAsync(CancellationToken cancellationToken)\n at Microsoft.Extensions.Hosting.HostingAbstractionsHostExtensions.RunAsync(IHost host, CancellationToken token)\n at Microsoft.Extensions.Hosting.HostingAbstractionsHostExtensions.RunAsync(IHost host, CancellationToken token)\n at EventStore.ClusterNode.Program.<>c__DisplayClass0_0.<g__Run|2>d.MoveNext() in /home/runner/work/TrainStation/TrainStation/build/oss-eventstore/src/EventStore.ClusterNode/Program.cs:line 120

Is there anyone who have an idea how to go on with the issue or who can tell me what information could be helpful to resolve my problem?

could you post your configuration & network setup ?

3

Configuration is added to the main post recently, what information can i provide you regarding to the network setup? Maybe you can specify that. IP Address and DNS Name you can look up out of the configuration.

4

Ext IP is a publicely addressable IP , is that IP address actually directly available on that interface ?
Meaning there is probably some natting going between the external world & the private network your machine is in.

5

Yeah, thank you! That was the reason. The public ip address is not routed directly, it is routed by something existing in azure. I just use the private ip address (which is reflected by the network interface) and now it is working.

I just only have an certificate problem, so my browser (windows) is asking me for an certificate. do you have any article or something else what can explain me what i have to do with this?

Kind regards,
Sebastian

yeah it’s a known issue, you have to click cancel or something and then it should work.
( only once, the browser will remember)
IIRC it’s in chrome / edge , Firefox should not have that issue
