UI not available

Hi all,
since a day or so, suddenly, I am not able to access the UI page on http://IP:8080.
OH is working fine, events are logged and rules are working.
But no access to UI from local network, both from desktop browser or iOS app.

It was perfectly working a couple of days ago when I last checked.
Probably the reason is that in netstat, there is no listen on port 8080.

Probably rebooting will solve it, but I want to understand what caused it.
What is the cause?

Here the output of netstat:

Anything in openhab.log? Anything in the browser’s console when trying to access the url?

Hi Rich,
when accessing IP:8080 there is nothing in browser console nor in openhab.log.
It simply remains waiting.

What is the process that starts the UI on port 8080? I could check in journalctl if there are any messages from it.

OH is all one process. Either it starts or it doesn’t.

If everything else in OH is running and there are no words in the logs when access or during startup the problem is most likely network related. Firewalls, host networking, misconfiguration, etc.

If the browser just spins until it times out that usually means it can’t even reach the address in the URL. Maybe the IP of the machine changed unexpectedly?

No Rich, the IP didn’t change.
I can access the tail log with http://IP:9001
Only http://IP:8080 is not working. Everything else is working perfectly fine.
And since few days ago also UI was working.
So part of OH or a service stopped working and I need to identify it to troubleshoot.

What can I do?

Please enter openHAB console with

openhab-cli console

and issue

bundle:list

check the output for non active bundles

Hi Hans-Jorg,
thanks for your reply.

^ It shows that the UI is running

What do you get back if you do a

curl localhost:8080

What port do you see behind this setting?

ps -ef | grep java | grep β€œDorg.osgi.service.http.port”

It should say -Dorg.osgi.service.http.port=8080
Write down the process id β†’ in my case 12313

what is

netstat -aon | grep β€œ8080”

saying?

what is

sudo netstat -nlp | grep 12313

telling you?

Hi Stefan
thanks for your reply.

Probably is not the UI that is not responding, is the port 8080 that is not listening.

No good news. All your commands are dead. :frowning:

This command just hangs. Need to press Ctrl+C.

openhabian@openhabianrpi5:~ $ curl localhost:8080
^C
openhabian@openhabianrpi5:~ $

This command doesn’t show anything:

openhabian@openhabianrpi5:~ $ ps -ef | grep java | grep β€œDorg.osgi.service.http.port”
openhabian@openhabianrpi5:~ $

Also this command doesn’t show anything:

openhabian@openhabianrpi5:~ $ netstat -aon | grep β€œ8080”
openhabian@openhabianrpi5:~ $

But, it was perfectly working until few days ago.
So something must have crashed in the system.

Did you try to stop openHAB, clean the cache (openhab-cli clean-cache) and restart openHAB ?

Please show

ps -ef | grep java

Can you do

sudo systemctl status openhab.service

What do you see in the logs?

no, as I want to leave the system as is to identify the cause.
If I restart and all comes back working I will never understand the cause.

Sometimes we cannot find the root cause but a restart and clean-cache solves the issue.
AFAIK you are the first with such an issue so somerhing might have gone β€žbezerkβ€œ on your system. Whithout any hints in the logs it might near to be impossible to find a root cause.

So you seem to have an issue wirh the OpenWebNet Binding.
Any changed from your side on that behalf?
Try to disable (bundle:stop) that Binding and check if that solves your issue

I notice that in the logs, even if it works fine.
Since last update in April/May it makes a lot of noise in the logs, but works fine.
The maintainer doesn’t seem active.

But should that affect the 8080 port?

I don’t know.
Even you don’t want it, I really recommend restarting an cleaning the cache.
It could be a simple, not reproducable β€žhickupβ€œ.

Here is the full log.
Full of garbage, but maybe you can get some useful information from it.

openhab.log on wetransfer (too big to upload here):

https://we.tl/t-3St9kUgx2D

I am ok that I might not get the root cause, but at least I would like to recover the situation and be able without restarting to reactivate the listening on port 8080.
It seems strange that there is no way to restart the listening on port 8080.

Any idea?

To be honest, it’s not the first time.
The issue randomly appears:

Since my last post on the matter, I have rebuild the OH installation, moved to verson 4, changed the hardware and the router…

But the problem is still there.

Ok, did not see that post. I will have a look at your logs later.
