Confluence PlantUML: rendering diagrams is ok, but cannot save


i wrote a simple diagram like this:




class test {}




it showed me a correct diagram after clicked "right arrow button".

but after i clicked "save button", an error occured.

the dialog said "Error rendering diagram. Please check your syntax."


and chrome console said like this:


Refused to connect to '' because it violates the following Content Security Policy directive: "default-src 'self' 'unsafe-inline'". Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback.



what should i do to resolve this problem...
