Operation 229 error: Unknown operation code (-2)

Hey everyone,

When I'm trying to connect on my self-hosted server, I get an `Operation 229 error: Unknown operation code (-2) `
I believed that this is an issue when joining lobby, however I don't have any idea what's causing the issue.

FYI I'm using the Photon Javascript SDK and I don't see any additional info regarding the error on the server logs.

Any idea what are the common scenario on getting this error?

Thanks!
