Check if there's another service running on this port. If so, this might be the reason for you cannot change the port. In case you still face issues, please paste your server.xml here.
Also don't forget to check if there's some firewall or antivirus blocking the communication
As mentioned by Arthur, to change the PORT JIRA listens to, just follow Changing JIRA's TCP Ports. However, please note that, in Linux, all ports below 1024 are privileged ports, and therefore only the root/super users can run services on these ports.
I have found a couple of articles discussing the best way to achieve this when running a service through a non-super user which may help you in this case:
Furthermore, you can achieve this either by using a proxy, to redirect incoming traffic to 80 to the JIRA port (8080 by default). Alternatively, you can also run JIRA as root, but that is not recommended in general (the fewer programs you run as root the better).
I hope this helps!
In addition, there's this documentation which describes how to run Confluence on port 80. This can also used to JIRA. https://confluence.atlassian.com/display/CONFKB/How+to+Configure+Confluence+to+Run+on+Port+80+Without+Apache+on+Linux Regards, Renato Rudniki
I have upgraded confluence to 6.1.2. it was successfull and we donot have any issue on any features but we are getting a pop-up every time we click on anything saying "can't check your base URL".
Could someone help me on that. I have checked proxy and its all fine.
Please help me asap.
