On-Premise MFA Server Connection Pool error.

On-Premise MFA Server Connection Pool error.

Set the value for max number of connections in the MFA Server Web Config to a larger value, in this case we set it to 100:  <add key="Connection.Options" value="max pool size=100" />

Optionally you can comment out the entry like this:
<!--add key="Connection.Options" value="max pool size=100" /-->
