Issue/Introduction
After upgrading Spectrum and VNA to version 21.2.2, the status for all domains on the OneClick integrated with VNA is "Waiting for VNA response".
I already fixed the missing username / passwords on the VNA side and all collectors show as "connected" on the VNA aggregator as described here:

However, the status is unchanged for five hours now. It seems like the issue described in
https://knowledge.broadcom.com/external/article/199594/unable-to-receive-alarms-in-spectrum-fro.html, but this is supposed to be fixed since NetOps 20.2.
The mysql output from the VNA Aggregator "mysql> show full processlist;" shows all VNA aggregator Daemons with a Sleep State.
Cause
Trouble shooting done:
- Verified the Aggregator to VNA collectors communication and do not see any issue
- After a manual on-demand sync from Spectrum no request was received to Aggregator and all domains are shown waiting for sync to complete.
- Restarted the OneClick server but the aggregator still has received no request.
- Enabled runtime debug on the OC web server “VNA Integration Information”
After analyzing the spectrum OC tomcat logs, we identified the hostname is changed from FQDN to a short name. The checkForActiveServer is false - the host name does not match.
from tomcat log.
