Hi @sunil390

Could you provide the MVS console log and the JCL, please?

I have two systems.

1. This issue is noticed when i connected remotely and then when tried to submit the Job. This system had only zowe vscode extention.
2. When tried to do the same from the system where TK5 is running the Job got submitted without any error. This system has zowe CLI installed alonng with vscode zowe extention.

@sunil390 We tried to reproduce this with the same dataset (TK5.INSTALL.CNTL(IEHLIST)) and VSCode Zowe extension — job submission works without issues on our end.

Since the problem only occurred on your remote setup, this might have been a transient network issue (NAT timeout, firewall dropping the connection, etc.).

Could you please:

1. Try again from the remote system and see if the issue persists
2. If it does, capture the MVS console log and any MVSMF WTO messages at the time of failure
3. If possible, use the trace proxy (tests/trace-zowe.sh --proxy) to capture the raw HTTP exchange

If the problem is gone, please close this issue. Otherwise we'll follow up in a few days.

Greetings @mgrossmann
Thanks for the feedback.
I have tried at different times and the pattern is hard on. Job gets submitted as seen in console but error reported in vscode.
Both my systems are windows11. Let me try running the script from git bash and share trace.
Pl. consider this at lowest priority!

[sunil390]

From the remote windows11 system i am able to delete Jobs! No errors seen.

[mgrossmann]

any news here?
Did you try later versions of mvsmf?

[sunil390]

Let me try and get back!
