Hi Aroldo, I'd recommend following our Troubleshooting Guide <https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error> to look for underlying errors when you see those error pages. It looks like you began that process (based on your screenshots as you discovered a hidden 403 Forbidden error in the UI). But, I'd also recommend looking at the backend logs to see if there's an error occurring at that level.
Generally speaking a 403 error means that you are being told you don't have permissions to access that endpoint. In this case, it's very strange that the REST API is returning a 403 on the root endpoint (`/server/api`). It could be that checking the logs of DSpace may provide more clues. But, I'd also recommend checking the logs of Tomcat (if you have it installed separately) and your proxy server (often Apache or Nginx)... it's also possible that something is occurring at the level of the web server or proxy that is blocking your access to the REST API. Overall, to me, at a glance, I'm not sure that this is a bug in DSpace. It's almost like something is occasionally blocking communication between the UI and the REST API. But, I'm not sure what that could be, which is why I'd encourage you to look for more errors in your logs. Hopefully if someone else has seen this before they will provide additional advice on this mailing list.
