IBM Watson Explorer Content Analytics 11.0.1 miner error /ui or /localhost:8393

After upgrading from WEXAC 11.0.0.0 to 11.0.0.3 ( or even to 11.0.1.0 ) the miner page is broken resulting in one of the following errors:

This issue doesn’t occur in version 11.0.0.0.

What’s the difference between 11.0.0.0 and the rest?

Environment situation:

Everything running on Linux RedHat

CL05 Running IHS 8.5.5.5 and WebSphere plugin point to CL06 ( Watson server 1 ) and CL07 ( Watson server 2 ) each running differenct collections.

URL for CL06 = https://server1.domain.com/ui/analytics    or /ESAdmin  hosted on CL05 ( IHS )

URL for CL07 = https://server2.domain.com/ui/analytics    or /ESAdmin  hosted on CL05 ( IHS )

Solution:

Change a propertie file: ../esdata/master_config/searchapp/Configuration.properties

Search for configuration={\”server\”:\”\”,

Change it to the frontend weburl: configuration={\”server\”:\”https://server1.domain.com\“,     (  or  configuration={\”server\”:\”https://server2.domain.com\“,    )

Restart the server and you are back in business.
