continue if 'subprocess.call' failes

[tester_V]

Hello!
I'm pulling out logs from remote hosts to my server for processing.
The server has a faceless account and all the Hosts have it added as an admin(admin group).
Sometimes, a new Host has a bad configuration and it asks for UserName...
I thought I can use try/except to keep going if an error or cannot log in...
for some reason, the code just stops with the message:
"The password is invalid for..."
I thought "try/except' will make it keep going but it is not:

try :
	subprocess.call("net use U: /delete /yes")
	time.sleep(1)
	subprocess.call("net use U: "+"\\\\"+itm+"\\c$\\SMTS\\TDR_Logs")
	tr = time.localtime()
	cutr = time.strftime("%Y-%m-%d %I:%M:%S", tr)
	print(f" Dir mounted -->> {cutr} -- {host_path}")            
except OSError as st :
	print(f" Error --> {st}")
	pass

Any idea on how to ignore the message ""The password is invalid for...""?
Thank you!
