Export Data: Prepare download nothing happens

[suntrop]

I want to move some sites to a new server/PL and need to export data.

I just upgraded to ghcr.io/plausible/community-edition:v2.1.0-rc.1 (ghcr.io/plausible/community-edition:v2.1.3 didn't work somehow).

But something is wrong with the WebSocket connections. The snippets on the /sites dashboard don't show any metrics and I guess the same problem with WebSockets on the export section. When I click "Prepare download" I get this error in the JS console:

WebSocket connection to 'wss://analytics.example.com/live/websocket?_csrf_token=RjMzRQcRaRwWOVYYCCMbAj12UwwEcREHpPZNuY9recfLxZhwCCgOW2Bv&_mounts=0&_live_referer=undefined&vsn=2.0.0' failed: There was a bad response from the server.

And nothing happens.

The PL logs last entries are Migration done! Migrations successful!
