Not working (stale information, information does not updated) after icinga2 update to version 2.11

Hi.

In log I see the following:

scheduler caught exception:

Hi

I seem to have the exact same Issue with my installation, updated icinga2 to 2.11 and now the dashing can't be started. Interestingly it starts on my system when I manually start it in foreground with environment variables.
ICINGA2_API_HOST=localhost ICINGA2_API_PORT=5665 ICINGA2_API_USERNAME=dashing ICINGA2_API_PASSWORD=**** dashing start

Seems the version regex returns a null/nil value whereas the call the first/last then fails - from #81. Can you query the REST API manually and extract the /v1/status/IcingaApplication endpoint and post it here?

curl -k -s -u root:icinga 'https://localhost:5665/v1/status/IcingaApplication?pretty=1'

Thank you for the fast reply!

Hmm, looks sane and in my tests, this version works as well. Can you both please share the content of the config/ directory? Please replace sensitive credentials.

I see, I made a programming mistake. I haven't coded Ruby for like a year now. The config reading is wrong with the new hard state option and old or local configs. Quickfix for you - add the new 'dashboard' option from the pull configuration file into the local modified version.
