  • h3. Summary Setting proxyUser and proxyPassword in the catalina.properties file breaks web proxy configuration h3. Environment * Any version of Confluence using SAL plugin 3.0.5 * Confluence 5.9.5 in this case h3. Steps to Reproduce # Use the following configuration in {{catalina.properties}} {noformat:borderStyle=dashed} #web proxy settings http.proxyHost=localhost http.proxyPort=8888 http.nonProxyHosts=localhost http.proxyUser=admin http.proxyPassword=admin {noformat} (i) Does not need to be a valid proxy server as we are testing against the nonProxyHosts (i) This problem also occurs if the proxy configuration is set in Confluence's {{setenv.sh}} rather than in {{catalina.properties}} # Start Confluence # Start JIRA on the same server # Attempt to create application link to the Stash server using the _localhost_ address h3. Expected Results The link should be created despite the invalid proxy configuration as {{localhost}} is whitelisted in {{http.nonProxyHost}} h3.

Notes Removing the the username and password field, despite using an invalid proxy ip and port, works as localhost is whitelisted as nonProxyHosts h3. Workaround Since the problem only affects configurations in which a proxy is used that requires credentials to be provided, a potential workaround is to change the configuration of the proxy server such that it allows connections from the IP address of the machine that Confluence is running on without requiring credentials. h3. Suggested Resolution Fix [SAL-350|https://ecosystem.atlassian.net/browse/SAL-350] and bundle the newest version of that plugin into Confluence.
