Graylog stopped

Hello All,

I am puzzled… i had my graylog integration working fine. After graylog stopped , caused by low disk space i expanded the disc in centos lvm.

At this moment, i can see the different graylog streams in librenms in the filterbar.
under all messages i can see my graylog streams, even a newly created one for test.
so it seems that the API is connecting.

but the result is always: no results found.

Any suggestions how to debug or what i do wrong?
