[opencms-dev] Upload of files larger than 15kb not possible

[Jan Michael Greiner]

Dear all,


it somehow has to do with the fact, that OpenCms is installed behind a reverse proxy (Tomcat with https://github.com/mitre/HTTP-Proxy-Servlet ).

If I do a port tunnel directly to the real server, and access the site with the real server's name, upload of larger files is possible.


What do I have to configure in the Websites configuration?
At the moment I have there the internal server's name. It seems not to work, if I put there the external servers name, but I will try again.
The external and the internal server are only accessible over TLS. But if I put https in the Websites configuration (Basic setup -> Server URL), when I open the dialog the next time, the https is replaced by http. Why is that?


Best regards,

Jan Michael Greiner

Dear all,


I have a strange behavior in my OpenCms 12 installation (Tomcat 9, jdk 11).

When I try to upload a file (click on Cloud with arrow in explorer view) larger than 15kb, the upload is stuck for some time, and then I get a dialog


Error

Attached are opencms.log and in catalina.log.

Does someone have an idea, why is that?
Uploading smaller files is no problem.
The problem happens with Firefox and Chromium.
