Hi Ciprian,

According to the first error you listed, the UI is attempting to contact the backend REST API using this URL:  https://elibrary.uaic.ro:8443/server/api

Does that URL respond for you? (It doesn't respond for me.)  If it's a valid REST API, it should return a JSON response which links to all the valid endpoints of that REST API.  For example, here's what the JSON response looks like on our demo API: https://api7.dspace.org/server/api

If that URL is invalid, then check your UI's configuration, specifically the "rest" settings in your environment.prod.ts -- as those settings are used to build that URL.

My guess is that your UI is misconfigured and is not accessing the REST API via the correct URL path. That's what the "No _links section found" error tends to mean.

Let us know on this list if that helps. Also, feel free to reference the Troubleshoot an error" page if you need more tips on finding errors: https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)
