Steps to Reproduce

1. Enable HTTP/2 in Clarity and HTTPS in Clarity.
   Add to <Service name="Catalina"> in the server.xml inside Tomcat's conf folder:
   <Connector secure="true">
  <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
</Connector>
2. Restart Clarity app service: service stop start app
3. Using Google Chrome and HTTPS URL, navigate to a project instance Status tab.
4. Preview the status report.
5. The PDF will be generated and previewed in the preview pop-up.
6. Using Firefox and HTTPS URL, repeat steps 3-4.

Expected Results: The PDF will be generated and previewed in the preview pop-up.

Actual Results: Error 'EXP-01000: Error generating PDF export'.

app-ca.log will show an error containing a line similar to: "net::ERR_INVALID_ARGUMENT at http://example.com/pm/#/project/5012345/status/5123456?print=true"

Environment

Clarity 16.4.2

Cause

As of Clarity 16.4.2, HTTP/2 is not supported.

Resolution

Disable HTTP/2 and use HTTP/1.1 instead.

HTTP/2 is not necessarily enabled at Tomcat level as described in the Steps to Reproduce - for example, it may be enabled at a Load Balancer or a Reverse Proxy.
