Hi,

Please follow our troubleshooting guide to find the details behind the 500 error.  It's not easy to provide any help without the error details. 

https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)

Once you locate the error details, if you cannot figure out how to solve the problem, you may wish to see if the error is one of the "common installation issues" listed here: https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-CommonInstallationIssues   If you still cannot find the solution, feel free to send the error messages to this list and hopefully someone here can provide support.

You don't need a web server or a reverse proxy for this unrecommended or unsupported configuration. If you have to have it you can stop the webserver or disable it and change your configs as you see it below. (For this to work you must have dspace version 7.3 or above).

# In local.cfg or dspace.cfg

dspace.server.url = http://myIP:8080/server

dspace.ui.url =  http://myIP

# In config.prod.yml

ui:
  ssl: false
  host: myIP
  port: 80

rest:
  ssl: false
  host: myIP
  port: 8080
  nameSpace: /server

1) yarn test:rest

2) yarn start:prod

3) Access DSpace at http://myIP

I try but it UI is not opening but back-end is working fine

$ ts-node --project ./tsconfig.ts-node.json scripts/test-rest.ts

        "dspaceServer" property matches UI's "rest" config? true

Stop Nginx or Apache and try:

# In local.cfg or dspace.cfg

dspace.server.url = http://52.15.74.25:8080/server
dspace.ui.url =  http://52.15.74.25

# In config.prod.yml
ui:
  ssl: false

  host: Server-IP (Server Private IP)

  port: 80

rest:
  ssl: false

  host: 52.15.74.25

  port: 8080
  nameSpace: /server

1) yarn test:rest
2) yarn start:prod
3) Access DSpace at http://myIP

I have successfully installed DSpace 7.5 in the AWS Ubuntu instance

I have followed the below mention things:

###############################

IN   local.cfg file

after edit this file restart the tomcat server

###############################

dspace.server.url = http://IP:8080/server
dspace.ui.url = http://IP:4000

###############################

###############################

IN config.prod.yml

after edit  the below lines and then run again the build command 

                        yarn run build:prod

###############################

ui:
  ssl: false
  host: 0.0.0.0
  port: 4000
.......

# The REST API server settings
# NOTE: these settings define which (publicly available) REST API to use. They are usually
# 'synced' with the 'dspace.server.url' setting in your backend's local.cfg.
rest:
  ssl: false
  host: IP
  port: 8080
  # NOTE: Space is capitalized because 'namespace' is a reserved string in TypeScript
  nameSpace: /server

###############################

###############################

dspace-ui.json

after edit the below lines then run 

pm2 start dspace-ui.json

###############################

   "DSPACE_REST_HOST": "IP",
   "DSPACE_REST_PORT": "8080",
   "DSPACE_REST_NAMESPACE": "/server"
