Port 8080 is used by other programs ERROR LauncherUI - Start-up failed.I. Unifi controller say port 8080 use by other. Unifi - Wont Start Port 8080 In Use. I am having this same problem. I couldn't find java running in processes. I also couldn't find a port 8080 that was running. I changed the port in data.systems to port 81 and it is still showing up as port 8080 is used by other programs. How can the answer be improved? Overview This article lists the ports used by the UniFi Controller. To learn how to change ports please see this article: Ports Used By default, the UniFi controller will operate on the following ports: TCP or UDP Port Number Usage UDP 3478 Port used for STUN. TCP 8080 Port used for device and controller communication. TCP 8443 Port used for controller GUI/API as seen in a web browser TCP 8880 Port used for HTTP portal redirection. TCP 8843 Port used for HTTPS portal redirection. TCP 6789 Port used for UniFi mobile speed test. TCP 27117 Port used for local-bound database communication. UDP 5656-5699 Ports used by AP-EDU broadcasting. UDP 10001 Port used for AP discovery UDP 1900 Port used for 'Make controller discoverable on L2 network' in controller settings. Hi all, This one has got me very frustrated! For some reason, all of a sudden one of our AP went down. Logged into the server and cannot log into the controller. Comes up with the error message - 'server taking too long to start'. All AP are working now, (had to reboot the problematic one) Looked at the ports that were being used and the ports that are being used (through TM) are from Java - which is right I believe? Needs Java to start up I guess. What I've tried: Updated the Java Updated the version of Unifi (from version 2.4 to 3.2) Tried to run the controller without Java Tried to end the Java Process Changed the ports from 8082 to 8081 and 8080. When I change the ports, it throws a different error message saying that port (blah blah) is in use. It is in use with Java. I noticed when I logged into the PC 'mongod' had crashed. I think this may have crashed because we were down to 1mb left on the server, which may have caused the controller to stop working. Cleared the space and have around 700mb left. Looked at the word document (which is 200+MB) and it cannot seem to find a error code. Looked at the server log and it brings these error codes: '[2015-02-12 11:42:34,721] ERROR LauncherUI - Starting UniFi Controller. [2015-02-12 11:44:35,603] ERROR LauncherUI - Server taking too long to start. [2015-02-12 11:44:35,607] ERROR LauncherUI - Start-up failed.'
