Don’t use the yellow bulb program. Close it and just go to https://localhost:9090. Openfire is already running as a service. Yellow bulb program is only needed if you don’t use the service.
I checked and found the program that uses the port, but the problem is that whoever is using the company’s ERP, so I can’t use it.
How can I change the openfire port? and what would be the suggestion?
Go to /openfire/conf, edit openfire.xml and change the ports (both regular 9090 and 9091 as you probably would want to use https instead of unsecure http to login to Admin Console).
Aconteceu isso comigo uma vez, e pra nao perder tempo, na instalação eu mudei a porta de acesso, tipo, de 9090 eu mudei pra 9091 e funcionou. Esse problema tem algo a ver com algum outro serviço da rede que nao consegui identificar.
