  • E07777 - Upload error: Could not upload file: 'C:\Users\...'
    • PKIX path building failed: unable to find valid certification path to requested target
  • HTTP-ERROR: 500 - (Internal Server Error)

  • HTTP-ERROR: 413 - Request Entity Too Large
    • HTTP/1.1 413 Request Entity Too Large

  1. Do the analysis of How to analyze http checkout error 404 or 500 (E30080, E30078) to check not working content or cache server.
  2. A 500 error is often returned from the cache server if the content server can not be reached.
  3. The error "Error Stream Closed transferring file" is often returned from content server because of firewall - or network security restrictions. 
  4. Component for Content Server issues: BC-SRV-KPR-CS. Needed information for creating an incident:
    1. OS, Content Server version, Content Server Patch level of the Content Server installation.
    2. Attach a copy of the ContentServer.ini / cs.conf file.
    3. (Windows only) attach the ODBC trace: See 1405031 - Generate ODBC trace on Windows

PKIX path building failed

The error " unable to find valid certification path to requested target" happens usually if you are using a self signed certificate that is signed by itself rather than a trusted authority.

The self signed certificat is not "trusted" by the JVM of ECTR (<ECTR>\basis\sys\win\jre64\lib\security).

=> Don't manipulate cacert of JRE, use an official CA signed certificate for your content server instead!

HTTP/1.1 413 Request Entity Too Large
