- Accessing <confluence-tomcat-sever>:8090/rest/plugins/1.0/?_=1590130083569 directly also works
- Only when accessing <confluence-reverse-proxy-base-url>/plugins/servlet/upm (i.e. the UPM screen) - the REST call to /rest/plugins/1.0/?_=1590130083569 fails with the net::ERR_INVALID_CHUNKED_ENCODING error
原因
It was confirmed that the Reverse Proxy (HAProxy) was the cause of the net::ERR_INVALID_CHUNKED_ENCODING error. The exact root cause from HA Proxy could not be reproduced in the Atlassian lab environment.
Work Around
Access UPM directly on Tomcat (i.e. <confluence-tomcat-sever>:8090/plugins/servlet/upm) bypassing the Reverse Proxy.
