The client and server cannot communicate, because they do not possess a common algorithm.

Error fix:

In web.config:

Add targetFramework=”4.8″ to <compilation

Example:

<httpRuntime requestValidationMode=”2.0″ executionTimeout=”6000″ maxRequestLength=”2097151″ targetFramework=”4.8″ />

    <!– <customErrors mode=”Off” /> –>

    <compilation debug=”true” strict=”false” explicit=”true” tempDirectory=”C:\Inetpub\vhosts\prod.aaronrich.com\tmp” targetFramework=”4.8″ />
