Apache error 503 when using ProxyPass:
Posted by jpluimers on 2016/12/05
When using ProxyPass (for instance within a Location) in Apache and you get an http error 503 (service unavailable), then usually the page/service to which the proxy directs to is dead.
I had this when shellinabox (forked from the old Google code repo) died on me.
In addition, ensure your ProxyPass statements contain a slash at the end your you will get a http error 502 (bad gateway):
