Configuring TLS setting on multiple server machines within same ecosystem

Question

Configuring TLS setting on multiple server machines within same ecosystem

Shivanand Sheelvant 1

Hi,

We have multiple instances of web service hosted on multiple Windows server 2016 machines.

We have a web service in one server machine and a service bus service hosted in another machine.

All the server machines have same configuration with respect to TLS or any security related settings.

We get the below error wen a webservice tries to connect to service bus service hosted in another machine
System.ComponentModel.Win32Exception (0x80004005): The client and server cannot communicate, because they do not possess a common algorithm

When both the services are hosted in same server machine, no error is shown.

The behavior is inconsistent.

Any inputs in this?
