We are using hosted mender on a Yocto-created distribution with meta-mender on [dunfell-v2021.01](https://github.com/mendersoftware/meta-mender/tree/dunfell-v2021.01/meta-mender-core/recipes-mender/mender-connect) and are facing the same issue.

The web ui shows exactly the same error as @Rohita83 posted above.

```
# mender-connect --version
mender-connect version 1.0.0 runtime: go1.14.7

```

Our `mender-connect.conf` looks like this:

```
# cat /etc/mender/mender-connect.conf 
{
    "ServerURL": "https://hosted.mender.io",
    "Shell": "/bin/sh",
    "ShellCommand": "/bin/bash",
    "User": "vps"
}

```

(Note: The `Shell` key got [defaulted to this value](https://github.com/mendersoftware/meta-mender/blob/dunfell-v2021.01/meta-mender-core/recipes-mender/mender-connect/mender-connect.inc#L44) by mender-connect.inc. It doesn’t do anything, as the correct key in mender-connect 1.0.0 is `ShellCommand`. The recipe sets the wrong variable. [This is fixed in \>= dunfell-v2021.03](https://github.com/mendersoftware/meta-mender/blob/dunfell-v2021.03/meta-mender-core/recipes-mender/mender-connect/mender-connect.inc#L39). This is totally seperate from what’s discussed in this topic.)

@Rohita83: Can you download files from your devices? When I try to download a file, the browser reports a generic “server error”. I also noticed that files which do not have a file extension get an extension `.json` appended automatically.

@manuel_vps you need to upgrade mender-connect to version 1.1.0 in the device to use file upload/download and port-forwarding.

@Rohita83 are you still experiencing the same error after upgrading mender-connect to version 1.1.0?

@Rohita83 can you please check the logs of the deployments service? According to the logs, you are receiving a server error (status code 503).

@Rohita83 no, I mean something like:

`docker logs menderproduction_mender-deployments_1`

EDIT: I see you posted the error. The serialization error means the deployments service cannot reach minio. Can you check your minio configuration is correct in the config, and you are pointing to the correct domain name?

What’s the fix on this error: “Artifact couldn’t be uploaded. Request failed with status code 413”?
