Hello, i am running Pydio on docker with reverse proxy from 8080 to [https://fqdn](https://fqdn)

```

its working fine  
now i installed the Cells sync client

connected my account  
but when i try to select a folder path, i get the following error

`all SubConns are in TransientFailure, latest connection error: connection error: desc = "transport: Error while dialing dial tcp 135. **.**.36:39793: connectex: No connection could be made because the target machine actively refused it."`

i thought it was a port issue, so i opened port binded port 39793:39793  
but then pydio wont work

How can fix this issue ?

Hello @Teal_c ,

Could you tell me which reverse proxy are you using ?

Your configuration seems right, the requirement for cells-sync are:

- to have TLS enabled (you seem to have the requirement on)

It could be related to your reverse-proxy config you have to proxy the grpc also,  
Take a look at this article (about nginx) it should give you more hints

- [Running Cells behind a Nginx reverse proxy | Pydio](https://pydio.com/en/docs/kb/deployment/running-cells-behind-nginx-reverse-proxy)

Hello,

Also from your config file, it seems like you are trying to use MariaDB 10.6.  
We have never tested it with Cells (to be honest, I was not aware it was out, but we will check)

Could you please already quickly try with an older version (most of the known installs use 10.3 and 10.4) ?
