Hi,
I am running OH2 on a RasPi (Raspberry Pi 3 Model B Rev 1.2) on Raspbian (Raspbian GNU/Linux 10 (buster)).
I ran file for several month and even today. I was configuring some MQTT devices and tested something this morning. Now it is afternoon and all my web pages (Paper UI, Basic UI) where unreachable.
I rebooted the system and it looks like OH2 is running fine again. But I still can not contact it through web page (port 8080, as usual). But still: no connection.
When checking netstat -anp|grep LISTEN
I get:
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 654/sshd
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 951/exim4
[...]
tcp6 0 0 :::8080 :::* LISTEN 586/java
tcp6 0 0 :::22 :::* LISTEN 654/sshd
So looks somehow it only listens on the IPv6 interface. But as usual, I am not using IPv6 here at all. Even if this would be the issue why did this happen out of sudden?
These are the interface settings:
3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether b8:27:eb:ba:96:dc brd ff:ff:ff:ff:ff:ff
inet 192.168.22.13/24 brd 192.168.22.255 scope global dynamic noprefixroute wlan0
valid_lft 5930sec preferred_lft 5030sec
inet6 fe80::76fa:c8e2:f722:eedc/64 scope link
valid_lft forever preferred_lft forever
Main question is how to resolve the isse and go back to IPv4. What file do I have to check for the configuration here.
Remember, I can not administer OH currently through website…
Thanks in advance for pointing to the right way!
