Environment

Product Version: 1.10

Cause

The 500 error in the logs originates when "about" tries to load SHA's for jars which only the tile uses, like the below.
 

org.springframework.web.client.ResourceAccessException: I/O error on GET request for "https://repo1.maven.org/maven2/org/springframework/cloud/spring-cloud-dataflow-shell/2.7.2/spring-cloud-dataflow-shell-2.7.2.jar.sha1"

Resolution

Check to see if the public internet access is enabled in the tile config? If so, disabling this feature will disable fetching the SHA and resolve this issue.
