Maybe something is using 9091 on your system. Check with netstat -a or Tcpview of 9091 is available and listening.
How do you run Openfire, via service or with a launcher?
hello @Lubomir_Hykl … Excuse me… i’ve the same problem , with openfire on https … Please can you tell me this alternative setup with java included x64 used by you?? can you give me a link?? thanks in advanced for your support…
I have ubuntu server 16.04 with openfire 4.3.2 and Java Version 11. At first it worked fine. But now I can’t access with any client anymore. Even access to console with localhost:9091 5 is not possible anymore. How can I fix that? Installation of openfire i do always with double click on ubuntu 16.04 gtk surface. A restart of openfire wasn’t enough. Complete restart of server solved the problem. Everthing is working fine now with ofenfire and OpenJDK: 1.8.0_191 Oracle Corporation – OpenJDK 64-Bit Server VM. Thanks for help! …
Good to hear that you’ve been able to work around the problem. Without knowing what the cause of your issue was, it is not feasible to tell you how to fix or prevent it. If it happens again, please look at the log files, to see if they hold any clue.
Openfire 4.3.2 is three years old. Ubuntu 16.04 is almost six years old. I recommend updating both.
