failed to get reader: failed to read frame header: EOF #520
Description
Activity
It means the connection is closed, by the other end or by a third party.
I got the same error today. In my case, nginx closed the connection after a timeout. My workaround for now is to set a longer timeout for nginx, but a proper fix is to use ping/pong messages to keep the connection alive. I come here to look for information about this.
What does this error mean?
