Hello,
we are using azure load balancer with two backend app servers running Blue Prism Server:7.01 under local system account. When I put loadbalancer DNS into the browser it return http error 405 "The website has a programming error." I'm able to run the server through browser from backend servers without any problem.
The following error has occurred:
SOAP security negotiation with 'http://serverIP:8199/bpserver' for target 'http://serverIP:8199/bpserver' failed. See inner exception for more details.
System.ServiceModel.Security.SecurityNegotiationException: SOAP security negotiation with 'http://serverIP:8199/bpserver' for target 'http://serverIP:8199/bpserver' failed. See inner exception for more details. ---> System.ComponentModel.Win32Exception: The client credential entered was invalid.

===================
I thought that maybe the issue could be that it's missing computer account that it could anthentificate with, hence I created it. After that I run setspn "setspn -S HTTP/fqdn:8199/BPServer hostname" what end up successfully.
Now when I run connection test from blueprism I got an error 404 "Ensure that the specified server address matches the binding configured on the server".
System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at http://fqdn:8199/bpserver that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. ---> System.Net.WebException: The remote server returned an error: (404) Not Found.

I already searched in blueprism documentations for all possible instructions and requirements, but I found almost nothing what could help me to figure out what could be the problem. any help here will be much appreciated.
thank you
