Error importing certificates | i-effect Handbuch

When importing certificate chains, an HTTP 400 error message may occur in the API (service subsystem). This is caused by an excessive amount of data in the HTTP header of the request.
As a solution, the value “maxHttpHeaderSize” in Tomcat can be adjusted.

Open the following file:

 \IEFFECT\V3R1M0\base\tomcat\conf\server.xml

Add this line to the “Connector” block:

maxHttpHeaderSize="65536"

The block should then look like this:

    <Connector port="22080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443"
			   SSLEnabled="true"
			   sslProtocol="TLS"
			   scheme="https"
			   secure="true"
			   maxHttpHeaderSize="65536"
			   SSLCertificateFile="/home/ieffect/webctrl/webctrl.crt"
			   SSLCertificateKeyFile="/home/ieffect/webctrl/webctrl.key" />

Then restart the *SERVICE subsystem.
