Client OS : Windows  
Client version: CellsSync - 0.9.2  
Revision ad58523870c3c03ec01b0f22800a27c572cf3aa3 (2020-09-10T09:43:57)  
Pydio Server OS: FreeBSD 13.1 (installed from ports)  
Pydio Server version: Pydio Cells Home Edition (v3.0.7)

This is a first connection issue.

When I try to create first account:

- I add proper URL to the Pydio Cells instance
- I click on login button
- Cell Sync open my browser, I see this URL:  
[http://localhost:3636/servers/external?manager=https://cells.my-domain.in](http://localhost:3636/servers/external?manager=https://cells.my-domain.in)

I briefly see server backdrop, then page becomes blank.

- Browser has page open, logged in to my Pydio account
- Tried with Firefox, Brave, Edge.

I see there is another issue here, not sure if related: [Cells sync cant connect to my server](https://forum.pydio.com/t/cells-sync-cant-connect-to-my-server/3986)

same her, I get a blank screen trying to connect

looks like something like this,  
[First connection issue: blank screen immediately after connecting to Pydio Cells server · Issue #46 · pydio/cells-sync · GitHub - https://github.com/](https://github.com/pydio/cells-sync/issues/46)  
an error message instead of a blank screen would help …

the example docker compose on [Pydio | Docker - https://pydio.com/](https://pydio.com/en/docs/cells/v4/docker)  
does work for me in browser, but not for cellsync with reverse proxy,  
for testing disabled tls … now it works
