Hello everyone, Can you guys help me with this issue?

I deploy the MONAILabel server on Ubuntu, I connect to that IP on Mac.  
The connection is okay, but when I push on the Next Sample button, I get this error.

The Python console show errors like this

```auto

```

The error is SSL but I don’t have experiments about that. Can you guys help me solve this problem?

Thank you!
