The RDM design server was not able to fulfill the request. Contact your administrator for help

[richardmgb]

I should start with the fact that I am an admistrator. So, I can't really contact anyone else. 

So, I am building a web process to a data provider. I've built the connection resource but when I go to Customer intelligence studio to build the web process using that connection resource, I get the error in the subject of this question. 

I need help with identifying the problem if anyone has experienced this before. I should say that I've done all this before multiple times but the difference this time is that the connection resource has a username and password. So, I am not sure if that's the problem.

Or if anyone know where the detailed logs for this error could be, that would very be helpful.

Thank you so much!

The error is related to the RTDM engine ,the connectivity between Web App server and the backend Data Base ( Teradata in this case).

As an investigation you can start looking at the 

1) the logs for SAS server 1,6 ad 7.

those logs located under /Lev1/Web/WebAppServer/SASServerX_1/logs and it is called server.log and SASDecisionServicesEngine6.4.logs (6.X -Version can be different)

2) 

"The RDM design server was not able to fulfill the request". - This is the error we get usually (The Screen shot also attached for the reference)

The root cause in our case was due to  failure at

com.teradata.jdbc.jdbc_4.io.TDNetworkIOIF.read() line number 663 in TDNetworkIOIF.java. The database reported "Incomplete LAN message header: read 0 bytes". (Please contact the provider of the database in order to investigate the problem.)

Resolution: Restart the Mid tier (Web Application Server) you can see all the events & RTDM Services in the CI Studio.

The the attached server.log shows the failure in com.teradata.jdbc.jdbc_4.io.TDNetworkIOIF.read(TDNetworkIOIF.java:663) :
