Anyone Getting Error with ServiceNow CMDB*

Hello,
Our ServiceNow version is New York and We have CMDB Integration and ITSM(I guess). But we have had a problem since July. We ran CMDB integration, we got an error after creating a report once or twice. Servicenow returned different errors always. For example: at first tried: returned ECC error, second tried: returning api/reports/123 not found. But when I check the API, I saw we already exists API endpoints and reports. After, when I check the Nexpose logs I saw an error as “Silo ID must be set”. We didn’t change anything on Nexpose or 1flow integration.
