Issue/Introduction

Unable to access Spectrum 24․3․7 landscapes using upgraded 25․4․4 OneClick servers during the upgrade process․​​‌​‍

SYMPTOMS:

• Inability to access Spectrum WebApp

• Limited access to Spectrum Web

CONTEXT: This issue occurs when attempting to use upgraded 25․4․4 OneClick servers to connect to existing 24․3․7 primary SpectroServers during a version migration․

IMPACT: Administrators cannot manage or access Web-based interfaces for 24․3․7 landscapes using upgraded OneClick components․

Environment

• Primary SpectroServers: 24․3․7

• OneClick Servers: 25․4․4

Cause

Security architecture changes between 24․3․7 and 25․4․4 impose stricter compatibility requirements, preventing newer OneClick versions from interacting with older SpectroServer landscapes․

Resolution

The version mismatch causes incompatibility due to security enhancements implemented between Spectrum 24․3․7 and 25․4․4․

STEPS: 1․ COMPLETE SPECTROSERVER UPGRADE Ensure all SpectroServers are upgraded to version 25․4․4 to match the OneClick server version․

EXPECTED: Access to Spectrum WebApp and Spectrum Web is restored once all landscape components align on version 25․4․4․

VERIFY SUCCESS:

• Log in to OneClick console

• Verify WebApp access on the 25․4․4 landscape

Additional Information

KNOWN LIMITATIONS:

• OneClick 25․4․4 is incompatible with SpectroServer 24․3․7 environments․

PREVENTION: Perform SpectroServer upgrades before or simultaneously with OneClick upgrades to maintain environment compatibility․
