Hi Petros, Based on your dspace.log, you are hitting a 500 error with this exception:
2021-11-30 14:33:55,594 ERROR unknown 8ffa97fa-9a7f-4ea9-9223-582e6535f9df org.dspace.app.rest.exception.DSpaceApiExceptionControllerAdvice @ An exception has occurred (status:500) java.lang.NullPointerException: null at org.dspace.app.rest.converter.ConverterService.toRest(ConverterService.java:107) ~[classes/:7.1] at org.dspace.app.rest.converter.ConverterService.toRestPage(ConverterService.java:203) ~[classes/:7.1] at org.dspace.app.rest.repository.SiteRestRepository.findAll(SiteRestRepository.java:64) ~[classes/:7.1] That exception/error seems to be saying that the Site object in your DSpace database hasn't been initialized (as it's returning null). This may mean that one or more of your Database migrations failed. You might want to run "./dspace database info" to see if there are any migrations that didn't run/succeed. If so, you can trigger them by running "./dspace database migrate". If all migrations ran successfully, you may force DSpace to recreate this Site object by running "./dspace database migrate force" from the command-line. Keep in mind, we also have a guide for locating error messages in DSpace 7 at https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove) This is useful to find the real error message either in your browser or in logs, so you don't have to send the entire files via email. If you run into any other issues, you also should check the Common installation issues at https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-CommonInstallationIssues Finally, let us know on this list if you run into any other problems which are not already listed in those common installation issues.

Over HTTPS with Apache2 and a LetsEncrypt certificate on my current temporary domain. https://s455778.name-servers.gr/ https://s455778.name-servers.gr/server/#/server/api The issue is that, when I access the frontend, I am greeted with a loading animation that goes on indefinitely (as per issue1.png). Moreover, that same animation behavior persists when I reach the first screen after logging in as an administrator account. Also, the sidebar seems incomplete (as per issue2.png). Attached is all the information that I have gathered around the system's functionality/configuration (the database password is hidden on local.cfg). I think I am meant to focus on the fact that dspace.log contains an exception on line 219, which has a trace right afterwards 2021-11-30 14:33:55,594 ERROR unknown 8ffa97fa-9a7f-4ea9-9223-582e6535f9df org.dspace.app.rest.exception.DSpaceApiExceptionControllerAdvice @ An exception has occurred (status:500) All the logs seem to be pointing to a possible backend or database issue... yet when using yarn config:check:rest, the frontend seems to be accessing the backend properly. What else should I check? Any recommendations or guidance would be highly appreciated!
