The error message seems to indicate a connection error.

This could be related to a query timeout or other failure. It would help to know how you encountered this error.

Were you running a large query? Small query? Can this error be reproduced at-will, or is it intermittent?

Where is your database hosted? Is it local? Cloud? What does the networking stack look like? Etc.
