this means that the OH2.2 service is not up and running properly.
Are you starting it using start.bat on windows or using a windows service?

There should be some useful info in openhab.log. Can you post some entries here to check them?

7

I have not setup the service as of yet im just running the start.bat as admin

what log would you like ? openhab log my mistake

8

How Can i send you the log having trouble

9

try to upload it to a file sharing service (e.g. google drive) and share the link here

edit: got it… .reading now :slight_smile:

should i be carefull sharing my log like that will it contain sensitive info ?

11

you should be careful and make sure that no username/password combos (or other critical info) is included.
you can remove it now from dropbox. i downloaded a copy
(so many errors are logged :frowning:)

12

I see alot of

IllegalArgumentException: Network prefix length is not within bounds

did you change anything related to the IP Address of the windows host running OH2.2 recently?
any org.eclipse.smarthome.network options configured in %OPENHAB_CONF%/services/runtime.cfg?

13

I see alooot of older? directories being used… most likely you had OH2 running from different locations in the past

C:\openHAB\
C:\OPENHA~2.0\
C:\Users\Sharpy\DOWNLO~1\OPENHA~1.0\
C:\PROGRA~2\OPENHA~1.0\
C:\Users\Sharpy\Desktop\C\OPENHA~1.0\

I would do the following if I was you: Instead of trying to debug every error and clean your OH2 deployment:
Install a new, clean OH2.3 Stable release and copy over your configuration files (items, rules, etc)

Also: Try to use a static IP Address on the host running OH2.3. DHCP based could cause issues when the IP changes. I see older IP: 192.168.0.54 and newer IP: 192.168.0.76 ?

14

I have noticed this error myself when i was looking at a kodi machine that was offline it gave this error saying uninitialized:Network prefix length is not within bounds what does it mean?

No i have not changed any IP settings

Yes i have moved it around in the past and then realised the folder should be called openHAB

Thats strange that is not the IP assosiated with my machine it should be 192.168.0.58 and like i say i have not changed any network settings IP .76 is a Google Home Mini .54 is a amazon fire stick so none of these are hosting OH

My Setup was created by PaperUI so i dont have all the text files atm im in the process of moving them over

The machine hosting OH has never had its IP address changed its always been 192.168.0.58 and it runs 24/7 so there is no chance something else stealing the IP

15

But where have the errors come from if it was working fine only two days ago

16

UPDATED Trying too acces localhost:8080 or http://localhost:8080/start/index gives this error 500

but accessing http://localhost:8080/habpanel/index.html#/ loads habpanel and seems to function fine
also accessing http://localhost:8080/paperui/index.html#/control loads paperUI and also seems too function fine it’s just the start page that is effected

there is no network config in services.cfgcf

17

A fresh start seems too have solved the problem of not being able too access the main page and brought a couple of my things back online that were stuck off because of a network error

A few more things too do yet top get my setup back too where it was
