'Meta endpoint! Unexpected status code: 503, with response body: None.'

Hi,
I have a weaviate instance running on K8 cluster on a GCP project.

While testing my code in debug model in pycharm, I connected to the weaviate instance and i did the mistake of stopping my program abruptly. My code has a finally block with wvt_client.close() so if i had run it it would have closed the connection.

Since it was closed abruptly i am unable to open any new connection. I get exception error “‘Meta endpoint! Unexpected status code: 503, with response body: None.’”

ResourceWarning: Con004: The connection to Weaviate was not closed properly. This can lead to memory leaks.
Please make sure to close the connection using `client.close()

is there a way to solve this without restarting the server?
thanks
