Hi, It sounds like you *might* have multiple issues based on those error messages.
First, there's the error that says "bind EADDRINUSE ::1:4000". That appears to be saying that you already have something running on port 4000 & PM2 is refusing to start something else on the same port. You may need to see if that's accurate, and if so, stop whatever else is running on port 4000. Here's some examples from StackOverflow on solving that issue: https://stackoverflow.com/questions/4075287/node-express-eaddrinuse-address-already-in-use-how-can-i-stop-the-process Additionally, there's the error that says "No _links section found at", which implies a communication issue between the User interface and REST API. This is one of our common installation issues with possible solutions listed at: https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-%22No_linkssectionfoundat...%22errorfromUserInterface If neither of those tips help, or you've already investigated those options, then we'd likely need more information about *when* these errors occur. Are they occurring all the time? Only occasionally? Can you get the User Interface to work at all?
