Confluence PlantUML: rendering diagrams is ok, but cannot save

[hisato.eguchi]

i wrote a simple diagram like this:

```

@startuml

class test {}

@enduml

```

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 'https://exp.stratus-addons.com/plantuml-2-2020-2/xxxxxxx' because it violates the following Content Security Policy directive: "default-src 'self' 'unsafe-inline' https://puml4cc.stratus-addons.com https://puml4cc-test.appspot.com https://connect-cdn.atl-paas.net https://ajax.googleapis.com https://aui-cdn.atlassian.com". Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback.

```

what should i do to resolve this problem...

Just had the same thing. It was working fine yesterday, but today, can't save.
