Overlay failed to load about kagerou

I also have this issue, here's the log from ACT when I try to load the overlay:

I had a similar issue. As it was explained to me, this is not an issue with Kagerou itself but rather with the Overlay plugin.

My error code looked like the following:

[9/19/2021 1:27:07 PM] Info: DPS Meter: BrowserConsole: Uncaught TypeError: Cannot read property 'v' of undefined (Source: http://kagerou.hibiya.moe/overlay/lib/listen.js?v=Northern-Cross, Line: 12)

Try using this URL instead of the default:

https://idyllshi.re/kagerou/overlay

[hibiyasleep]

it's usually network issue (it isn't usual in 2021, but this is 2010ish product still) more than kagerou's issue, so try some Refresh on overlay, or delete (ACT folder)\OverlayPluginCache\Cache.

Confirmed on OBS and ACT Overlay. A clearing of cache fixes the issue.
