hello everyone… i need help accessing my openhab from another device… so far everything worked ok… today i ran influxdb and grafana… everything works as it should but directly on my debian… (by the way i updated Azul JDKs Java) this is the only change so far… I don’t know if it has anything to do with this… but after these changes remote access from other computer/browser 192.168…:8080 stopped working, same it’s on android app… can’t access openhab. the only link that works is myopenhab.org
can anyone direct me on how to solve this?.. I can’t control my home through applications and browsers at home…

As you are able to login via ssh I assume that you know which name/IP to use in the browser. First thought was that the OH server IP address may have changed in your network.
Login to vi ssh and run
sudo netstat -tulpn | grep java
This will show all the listening ports and used interfaces that are related to the java process.
It should look similar to
How does it look in your case ? In case you use port 8080 then especially what is the output for that port.
Is a network interface or the local loopback interface related to that port ?
Should be fine. Port 8080 ( should be http port ) and port 8443 ( should be https port ) are listening on tcp6 network traffic.
what does that exaclty mean ? Do you use a browser on your debian system and you use the hostname to access your openhab instance or do you use IP address ?
I mean is that if I open the site on my intel nuc - debian in the browser I open localhost:8080 and I have access to openhab. Until now, I could enter on my laptop or tablet in the browser
192.168.18.194:8080 and I had access to openhab… I didn’t do anything special, just what I described above, i.e. influxdb installation, grafana and java update… then in the evening I saw that access from other devices is not available… “ERR_CONNECTION_TIMED_OUT”
In the android application it is the same, access to openhab does not work … “HTTP 404”
That are two different things.
ERR_CONNECTION_TIMED_OUT means that the host is not reachable or blocked by a firewall.
HTTP code 404 means that the host is reachable but the page it is trying to address/download is not there.
Is there any error message in the /var/log/openhab/openhab.log file ?

I managed to solve this problem some time ago… forgot to write about it.
When creating the samba server I wanted to add a port to the firewall… and it turned out that all ports were removed… along with openhab… I can’t explain it rationally but it seems to be some problem with influxdb because after its installation it happened and only this port was in the firewall…
finally i added the openhab port to the firewall and everything started working.
Regards
