library has correct "data server" definition defined. i also checked that none other same engine library has same tag name
we have alias in place for server names - is that a problem? if that is the case then i believe "server definition" + authorization service definition needs to be changed with alias name instead straight server name, isn't it?
sorry, i overlooked. server definition and "lasr authorization service" definition is correct, no alias name mentioned anywhere for any midtier server.
so problem still there, somehow display libname statement showing SIGNER="https://midtier-alis:443/SASLASRAuthorization" ;
I am assuming that these tasks previously worked as expected in your deployment.
You indicated that you have changed some components of the configuration, including the proxy server.
I recommend that you open a discussion with SAS Technical Support. Be sure to provide specifics about your OS and infrastructure, as well as changes you have made to the SAS configuration.
