A new SpectroSERVER was installed in a DSS (Distributed SpectroSERVER) environment, but the OneClick web server cannot access it.
There could be a few communication issues causing this.
1. Hostname cannot be resolved and missing hostname in the Host Resource Configuration (.hostrc) File
2. Network/firewall blocks access
3. Tomcat cache needs to be refreshed
CA Spectrum 10.x
#1: Added the IP/hostname pair in the Windows hosts file.
Added the hostname in the .hostrc file via Spectrum Control Panel - Host Security
#2: Disabled internal firewall on OneClick host
#3. Restarted Tomcat service on OneClick host
