I recently upgraded Openfire Server from 4.8.1 to 5.0.3. Since then, I cannot access the admin side whether it is on the network or from the host server itself. I have gone to the openfire.xml file and verified that the line 127.0.0.1 is deleted. Here is a screenshot of the error I get:
Could you maybe check the logs at startup? if you’re on linux, it should be under /usr/share/openfire/logs/
See if there’s any error concerning the admin page?
This does not ring a bell with me either. As @iro wrote, it would be very helpful to know what Openfire logs at startup. Have a look at the logfiles, but also the console output and things like syslog.
