So far it is clear, that Cacti authentication works and graph data is delivered to RackTables image proxy. The data is probably damaged on its way to RackTables HTTP client. Could you retry the IMG SRC URL again to tell if RackTables server HTTP response misses headers, body or both? Are there any extra bytes, which should not be there? In the RackTables server access log, what are HTTP response code and content-length for relevant requests (module=image&img=cactigraph)? -- Denis Ovsienko
