Hi Cristiane, In order to help, we'd need you to look for the underlying error message when you attempt to access the User Interface (or backend, depending on the problem). Here's a troubleshooting guide with details on finding the underlying error: https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)
We also have a list of common installation issues at the bottom of the install instructions. It's very likely you may be hitting one of these common problems (but it'd be easier to tell which one after you look for underlying errors): https://wiki.lyrasis.org/display/DSDOC7x/Installing+DSpace#InstallingDSpace-CommonInstallationIssues If you can find more information about the underlying error, it'll be easier to help. You also could try initially running the User Interface manually (not in PM2) just to verify your other configs are correct. That would at least help ensure you have a correct configuration between the frontend & backend. This is documented in step 6 of the Installation for the UI.
