After updating Cells Home 2.0.8 to 2.1.11 I am no longer able to add an account to CellsSync 0.92.

Response received from Cells is that the redirect\_uri is invalid.

Cells installation is behind a traefik reverse proxy. In this case the proxy does not appear to be the source of the issue as was found to be in similar topics (but with gRPC errors).

Hi, there have not been changes on this area between 2.0.8 and 2.1.11  
Can you post the pydio.json section with the “staticClients” ?
