Since Monday I have a problem.
After restarting my host server Windows Server 2016 and the openHAB 3.1 server, openHAB can no longer connect my GIRA IP interface.
The restart was necessary because of a Windows update. But nothing has changed with centOS and openHAB.
My openHAB ran on Hyper-V virtual centOS 8 for several months without any problems.
I only have one GIRA KNX IP interface.
The IP interface can connect 4 tunnels, but I use maximum three systems to connect to the bus. (ETS, Tobit David and openHAB).
If I enable the thing I get the following log:
16:46:01.695 [INFO ] [hab.event.ThingStatusInfoChangedEvent] - Thing ‘knx:ip:KNXGateway’ changed from UNINITIALIZED (DISABLED) to INITIALIZING
16:46:01.722 [INFO ] [hab.event.ThingStatusInfoChangedEvent] - Thing ‘knx:ip:KNXGateway’ changed from INITIALIZING to UNKNOWN

My thin is configuratet as follow:
label: KNX/IP Gateway
thingTypeUID: knx:ip
configuration:
useNAT: false
readRetriesLimit: 3
ipAddress: 192.168.10.112
autoReconnectPeriod: 60
localIp: 192.168.10.113
type: TUNNEL
localSourceAddr: 0.0.0
readingPause: 50
portNumber: 3671
responseTimeout: 10
localIp is the IP adress of the openHAB server
In the KNX project, the localSourceAddr is actually 1.1.1 but I tried this too
I tried the following:
- switch the IP interface off and on again
- reprogram the IP interface
- Changed the switch port and switched it off and on
- restart all server
- binding and thing deleted and reinstalled
- booted old clean saved image
- try router mode
- closed all other software (tunnels)
- searched the whole internet
But openHAB still cannot connect. My ETS can almost always connect. Only sometimes I get the message that no more tunnels are available.
But when I stop ETS there must be a free tunnel.
How can I see more than in the log? Can I display the existing connections? What else can I try.
A new IP interface cannot be the solution, it works perfectly with ETS and Tobit David.
Thank you for ideas and hlep…
