"sftp: Unexpected end event raised by server" after inbound request for a channel window adjust

Hi there, I am facing a strange issue where I am trying to connect to an sftp server and grab a file. Im able to connect to the sftp server but it makes a request to adjust the channel window size and then fails 5 minutes after receiving the request. I have been able to connect to multiple other servers without issue, some of which also made requests to adjust the window size and this is the first instance where its failed. I think this may be some sort of misconfiguration on the SFTP server but I have no idea what that could be. Im hoping that someone more familiar with the project might be able to help me figure out what is going wrong here. Any suggestions as to what I could try?

Here are the relevant logs:

@richard-peters It will be merged. I wanted to confirm the fix with @kelly1266 first.
