ssh paramiko can't read xlsx files - sftp

Question

I use paramiko to ssh
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy( paramiko.AutoAddPolicy() )
ssh.connect(Hostname, username=Username, password=Password)
ftp = ssh.open_sftp()
files = ftp.listdir()
dir_oi = "directory_of_interest"
foi = ftp.listdir(dir_oi)
and can find a read a csv successfully with:
remote_file = ( dir_oi +"/" + foi[-1])
with ftp.open(remote_file) as f:
df = pd.read_csv(f, sep = '\t', header = None)
the minute I change remote_file to an xlsx, with
with ftp.open(uw_remote_file) as f:
df = pd.read_excel(f)
I get the error SSHException: Server connection dropped: or Socket Closed
of note, I can run this line without any error existing_xlsx = ftp.open(uw_remote_file)
Any suggestions how to overcome this?

I can download using
filepath = uw_remote_file
localpath = "test.xlsx"
ftp.get(filepath,localpath)
so will go down that route and delete after use

Answer 1

From the log it looks like it were able to open both files. pandas is running into EOF error, So, which means excel file is completely empty.
Can you confirm if that is empty.
