Hi Leonardo,

When logged in on your frontend, can you successfully curl https://repositorio-digital.uap.edu.bo/server/api?

Having taken a quick look recently:

The backend server is serving content at https://repositorio-digital.uap.edu.bo/server/api
The frontend server is serving content at https://repositorio-digital.uap.edu.bo/

Checking web inspector in your browser, it says it can’t find the _links, which is clearly available from point 1.

So, check on your frontend server that it can reach the backend server under the same name that web clients us.

Hi Sean
I already checked the logs for dspace, tomcat9 and also postgres showing that they are active, the tomcat9 (AJP) and postgres settings are the same as they are in lyrasis but it still shows me the same error 500.

As I have dspace and apache separated in different ubuntu machines they should be together in one machine?

The Chatgpt says to change the rest with the domain name plus the local IP. I did it and it accepts these settings but I still get the 500 error.

Hi Leonardo

When I try repositorio-digital.uap.edu.bo on port 443, I get a 500 Service Unavailable error.

This suggests to me that your configuration is correct, but that your backend service is not running.

Check your dspace and tomcat logs.

when I put in the host in the “ui” my institutional domain I get the error 500 but when I put the localhost error 443 or 503, because they are separated virtual machines ubuntu where I install the dspace and where an engineer is in charge of the ssl and there is also the apache.
I did not install any nginx or apache in my local machine even it works without having it installed, because it was blocking the exit with the domain where the apache is.

I leave it with localhost or with my domain?

I rechecked the tomcat to see if it is failing to communicate with the dspace server but it is working normally.

I am reinstalling dspace again with the lyrasis instructions if I missed any command. When I finished the installation I followed the same ssl settings with this guide: https://repozitar.fhv.uniza.sk/items/5b8d7e58-8e9c-4280-85d3-9d7c4b49b4d7
but still the error 443 or 503 if I change in the “ui” to localhost but I put my domain it comes out with error 500 also I press the dspace logo and it loads its normal dspace startup, but I reload the page and it comes out again with error 500.

in pm2, ui:host variable have to be domain(pointing to ip accesible) or ip accesible, because if you use localhost, pm2 is gointo to answer only localhost requests.

Hi Sean
if i put localhost i get error 443 and the ssl certificates are already enabled in apache, could you guide me on what i am failing please.
my ubuntu virtual machines are separated, in one I was assigned to install dspace where I follow the steps of lyrasis works well locally but with a domain is failing and the other engineer is the one who manages the apache and ssl certificates showed me that the domain is already public but I still have difficulties with the dspace when I want it to be public for my institution.
1. i made the changes to localhost but now i get error 443.
2. in the firewall (ufw) in both already assigned the firewall, also in the /etc/hosts I assigned the private ip where I installed the dspace and apache.
3. in the java it is listening with the ajp of the dspace that I configured.
4. I asked again for new ssl certificates but it continues with the error 443.

Hi Leonardo

I think you should have 'localhost' in the ui section of config.prod.yml:

ui:
ssl: false
host: localhost
port: 4000
nameSpace: /

Good morning to all the community I need your help I have already checked all the solutions of the error 500 of the community but the error does not disappear.
My institute gave me a machine to install dspace and I configured it and made the changes so that it is with my domain of my institution with the guide of lyrasis, I followed the common problems of dspace but still I can not solve the error. Could you help me please.
0. en una maquina tengo el dspace y en la otra apache con los certificados SSL habilitados. nota: donde esta instalado el dspace no estoy ocupando apache o nginx ya que puede funcionar sin ocupar esos dos.
1. in the conf.prod.yml I left it with my domain because if I put “localhost” I get error 443 and if I leave it with my domain I get error 500.
3. in the conf.yml is the same as conf.prod.yml
4. in the dspace-ui.json I already made the changes with port 443 and my domain name.
5. in the local.cfg I put my domain.
the dspace server loads normally but the front end with error 500 I enabled the ufw “8009,8080,4000,80” on both machines.
