Need Help Please Windows Installation 404 error - OH2

Setup, Configuration and Use Beginners
1

Hi,
I have read the entire setup process for Windows 7 several times and I have removed all installs, rolled back my windows setup to ensure there were no traces of the install and reinstalled twice and still just get this 404 message when I try to connect through the browser to localhost:8080.

Access Error: 404 – Not Found

Cannot locate document: /

My setup is:
Windows 7
Installed the newest Oracle Java from the link in the documentation
I have added the JAVA_HOME environment variable to point to my java install directory
I have tried to install OH in a couple of different locations, currently at C:\OpenHab
The Karaf window opens and everything seems to load and I get the OpenHab prompt and I can see that the uptime stat increases the longer it runs.

shell:info contents below

Hello there I have exactly the same issue (and have followed the same steps), but on a Windows 10 system. Any help would be appreciated!

Check the firewall settings and make sure it isn’t blocking port 8080.

Look for errors in openhab.log. You could also run log:tail within the Karaf console to see what is being logged.

You wrote:

localhost (the loopback adapter) is always 127.0.0.1, but openhab should run on the IP assigned to the LAN adapter, not the loopback adapter. Did you try connecting to IP-OF-PC:8080?

This is my very first install, but have same problem. If I enter to browser: ipofpc:8080 throws error 404
Firewall was disabled, no change.
Checking the above suggestions the log file ( d:\openHAB2\userdata\logs\openhab.log) has zero length.
I copy below the shell:info and the beginning of log:tail.
Full log:tail is very long.

Any help would be appreciated…

You have some other program running that is already bound to port 8080. You either need to stop that program or change the default port OH tries to use. Unfortunately, I’m not sure how to change the ports OH uses in Windows.

Thank you, that was the problem, however I have no idea which software uses 8080.
It is easy to change port, in windows command prompt to eg. 8081 by setting a system variable:
set OPENHAB_HTTP_PORT=8081
Then OH started normally :grinning:
