Intermittent Proxy Error: Mavericks Server
I have MXToolbox running periodic checks on my Mavericks Server (v3.2.2 on OS X 10.9.5), and I get notifications daily that the server is down. Usually, when I then check the hostname via browser, I am able to connect, but often the Wiki icons don't show up. I just get the spinning "loading" graphic. If I refresh the page, it tends to reload just fine.
Today, I got the same partially loaded wiki page, and instead of reloading, I clicked the "lock" symbol to log out, and the server threw this 502 Proxy error:
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /wiki/.
Reason: Error reading from remote server
Refreshing the page results in the Wiki service responding normally again.
I am appreciative of any help I can get.
Mac mini, OS X Mavericks (10.9.5), Server 3.2.2
