...原因
1) Synchrony is using the URL, http://127.0.0.1:8091/synchrony which should be escaped by the forward proxy.
2) There is a misconfiguration on the reverse proxy level such as the wrong Synchrony port being used.
ソリューション
1) Follow the configuration described in our Configuring Web Proxy Support for Confluence documentation:
If you're using Confluence 6.0 or later with Synchrony, you'll need to pass the following to ensure Confluence can connect directly to Synchrony.
Replace localhost|127.0.0.1 with your Synchrony IP if you have used the synchrony.host system property to change the IP Synchrony uses.
-Dhttp.nonProxyHosts=localhost|127.0.0.1 -Dhttps.nonProxyHosts=localhost|127.0.0.1Note: You may need to escape the pipe character | in some command-line environments.
If the http.nonProxyHosts property is not configured, all web requests will be sent to the proxy.
Remember to restart Confluence once the change is implemented.
2) If you are using the direct connection to the Synchrony port at the reverse proxy level, check your reverse proxy configuration and make sure that /synchrony requests are redirected to the correct Synchrony port which is 8091 by default.
