Environment

Release : DX NetOps Spectrum 10.4

Component : Spectrum Core / SpectroSERVER

Resolution

When re-configuring the OneClick Webapp to use HTTPS with OneClick the hostname was changed from
localhost to a FQDN. For some reason, there appears to have been an issue resolving this resulting in the
reported behavior SESSION ENDED.

-host 10.10.10.15 -port 8443 -ssl true -contextPort 43000 -compress 9

Changing the -host parameter from the FQDN to the IP or localhost and now it launches properly.

Additional Information

This should be addressed in the 10.4.1 release
