Hallo,
Installed DSpace7 beta5 and got tomcat9 running on localhost:8080 and
dspace-angular on localhost:4000
I can reach the HAL Browser, log in and request all the stuff that's there.
I started dspace-angular with yarn run start:dev which ends with
** Angular Live Development Server is listening on localhost:4000, open
your browser on http://localhost:4000/ **
: Compiled successfully.
my environment.dev.ts is
export const environment = {
ui: {
ssl: false,
host: 'localhost',
port: 4000,
nameSpace: '/'
},
rest: {
ssl: false,
host: 'localhost',
port: 8080,
nameSpace: '/server'
},
};
When trying to connect to localhost:4000 with the browser, I see the
DSpace angular header and moving sot. In the developer console I found
the error:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading
the remote resource at http://localhost:8080/server/api.
After searching a while I found a similar thread on gihub
(https://github.com/DSpace/dspace-angular/issues/1036) and set
rest.cors.allowed-origins = ${dspace.ui.url}, http://localhost:4000,
http://localhost:8080
I did not set proxies.trusted.ipranges according to
https://github.com/DSpace/DSpace/pull/3171.
Any ideas what I have missed?

Hi Armin,
That's unexpected...but, let me ask a few questions to make sure I understand your setup correctly & am not making assumptions.
1) I'm assuming both the UI and the backend are running on the same machine/server? That's the only way you can run them both on 'localhost' under HTTP...otherwise, at least the backend needs a valid, public URL and be running under HTTPS.
2) Is the backend/REST API accessible in your browser at
http://localhost:8080/server/ ? It should be, as that's the URL your UI is trying to use.
3) Could you verify there are no other errors in your Tomcat logs? Sometimes if Tomcat throws a major error, it can result in a CORS error (as a side effect of the larger error)
Finally, we have started to create a guide for "Common Installation Issues". Check out the advice in that section to see if any of it is helpful : https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-CommonInstallationIssues
If you figure it out, please let us know what it was. We have found a variety of scenarios that can result in these sorts of issues (hence the guide) and we're trying to document them all. So far, though, the problem has always been a configuration issue....so,
I'd recommend taking a closer look there first. But, glad to try and offer more advice if you are still hitting issues.
Tim

to DSpace Technical Support, "Tim Donohue ...@lyrasis.org
I'm sorry. Like so often, I located the error in front of the keyboard.
After your mail I double checked the Common Installation Issues section
again and the https://wiki.lyrasis.org/display/DSDOC7x/REST+API page.
And everything seems to be alright.
But what I have overseen was my SSH-tunnel connection.
Just to clarify:
I work on my development PC and had DSpace7-Rest and DSpace-Angular
running on ports 8080 and 4000.
I afterwards installed DSpace7 on a local server for my collegues to
access and test it. And that server doesn't have a grafical interface.
Because tomcat and dspace-angular are configured to accept only local
connections I had set up a tunnel from my development PC to the
dspace-server (-L 5000:localhost:4000, 4000 was occupied by my local
installation). And therefore my browser connection was http://localhost:5000
After adding localhost:5000 to rest.cors.allow-origins it works.
With that in mind I also got the installation with apache on top running.
Thanks for your help and may my error help somebody else.
