1. Spectrum services not reachable if Spectrum and SSA are on separate machine
2. If Spectrum and SSA are on same machine, Spectrum installed on the specific port might be blocked.
3. Spectrum is not licensed

1. For Spectrum services not reachable issue, make sure the Spectrum and SSA machines can ping each other.

2. For port issues, make sure the port is open for Spectrum (default is 8080).
Recommended: After Spectrum is installed, try to launch Spectrum to make sure Spectrum was installed without any issues.

3. Check if Spectrum is licensed. If you already have the Spectrum license key, follow the Knowledge base article on how to install permanent Spectrum license.
