Web Interface of openHab 3 not reachable

Setup, Configuration and Use Migration
21

openhab.log, audit.log, and events.log are empty (all have 0 byte).

22

This check says (seems to be right):

openjdk version "11.0.9" 2020-10-20 LTS

Good idea, I’ll do that (remark: the port 8080 and 8443 are used by a unifi controller, thats the reason why I configured OH to use 8088 and 8053) …

… I did that but it didn’t change anything. I think I’ll do a clean install of OH3 on another Raspi.

23

I never succeeded in changing ports for OH3 on docker for one reason or another. My use case was on a synology with also a unifi controller. I changed the unifi ports and openhab worked on the standard ports. So i kept it that way…

Not really right Java version.
We strongly recommend Zulu 11, not OpenJDK.

Same thing happened to me today. I’ve been working two days building up everythng with OH3. During this time I have occasionally being having problems with the web interface - the content didn’t load. Now I can’t see anything. The browser just tries to update the page. Frontail doesn’t show any errors in the logs. I have been waiting for about hour now. This is very frustrating, since there’s still a lot to do. If this is just too early version…

I didn’t install that manually, that was what openhabian-config installed automatically … the full version info looks like this:

openjdk version "11.0.9" 2020-10-20 LTS
OpenJDK Runtime Environment Zulu11.43+88-CA (build 11.0.9+11-LTS)
OpenJDK Client VM Zulu11.43+88-CA (build 11.0.9+11-LTS, mixed mode)

Is this the right one?

27

Yes, the complete version string shows correct version installed.

I want to state that this is some sort of browser issue. With another computer the web pages worked fine, but with this computer the pages are still trying to open… Refreshing the page with Ctrl+F5 doesn’t help.
Microsoft Edge on both computers.
I’m using a separate browser (Edge) when setting up the OH3. It is easier to switch between browsers since the icon looks different :smiley:

I am having bit of a similar issue, i m in windows 10.

  1. I installed OH3 in windows 10 (basically set java home download and extract)

  2. run OH3 and confirm it was working fine

  3. updated the \runtime\bin\setenv.bat HTTP_PORT=8099

  4. Confirm the web ui was available in new port. All working good.

  5. Then i decided to make OH3 as a service and did the steps in documentation to make OH3 service again all good.

But if i start OH3 as service the web ui port is 8080 not 8099 as set in the setenv.bat (and in setenv) file.
But if i stop the service and start OH3 via command prompt the http port configured in setenv is being used as 8099.

Now i am scratching my head how do i make sure my OH3 as service uses the port configured in setenv.
Can some one please help.

P.S i have i don’t have any \etc\default\ folder.

Have you followed these instructions and changed the port here ?

wrapper.java.additional.14=-Dorg.osgi.service.http.port=8080
wrapper.java.additional.15=-Dorg.osgi.service.http.port.secure=8443

Sorry for the reply. I totally missed that config ( should have tried the search function in the config file as well than skimming it visually).
Long story short i changed it and the OH3 as service is starting 8099 port.

Thanks for the help

Unfortunately I ran into the same problem auf upgrading from 3.4.2 to 4.0.1 :frowning:

openhab-cli info says:
Version: 4.0.1 (Build)

User: openhab (Active Process 692)
User Groups: openhab tty dialout audio bluetooth gpio

Directories: Folder Name | Path | User:Group
----------- | ---- | ----------
OPENHAB_HOME | /usr/share/openhab | openhab:openhab
OPENHAB_RUNTIME | /usr/share/openhab/runtime | openhab:openhab
OPENHAB_USERDATA | /var/lib/openhab | openhab:openhab
OPENHAB_CONF | /etc/openhab | openhab:openhab
OPENHAB_LOGDIR | /var/log/openhab | openhab:openhab
OPENHAB_BACKUPS | /var/lib/openhab/backups | root:root

URLs: http://192.168.178.98:8080
https://192.168.178.98:8443

But these 2 links don’t open the web interface. „Site can not be opened“ and iOS app doesn’t work aswell. Any ideas?

Edit: after
sudo apt-get install openhab=3.4.5-1
and
sudo apt-get install openhab-addons=3.4.5-1
everything looks good again. Web interface perfectly reachable.

Why does it not work with 4.0.1?

33

Did you install Java version 17 when you switched to 4.0.X ?
Based on the steps / information you provided I would assume that this is not the case.

34

You were right. Java 17 was not installed.
Now:
openjdk 17.0.7 2023-04-18
OpenJDK Runtime Environment (build 17.0.7+7-Raspbian-1deb11u1rpt1)
OpenJDK Client VM (build 17.0.7+7-Raspbian-1deb11u1rpt1, mixed mode, emulated-client)

But web interface doesn’t show up again. :frowning:

Edit: Solution in my case:
Stop openHAB service, clear cache and reboot.
Too simple… :wink:
