In a API Manager clustered environment (in my case, I have a publisher, a store, two gateway nodes and two key manager nodes fronted by a WSO2 ELB 2.1.1), while regenerating tokens, if you come across an error saying with an exception as below at Key Manager node, then this is due to a configuration issue.

This is what you have to do to solve this issue.
1. In you Gateway nodes, you need to change the host and the port values of the below APIs that resides under $APIM_HOME/repository/deployment/server/synapse-configs/default/api
_TokenAPI_.xml
_AuthorizeAPI_.xml
_RevokeAPI_.xml
If you get a HTTP 302 error at Key manager side while regenerating the token, make sure to check the RevokeURL of the api-manager.xml of the Key Manager node to see if it is pointing to the NIO port of the Gateway Node.
