Issue/Introduction

Using GMU browse  command locally on the  gateway ( Destination gateway  ) , gave us misleading error that we usually see with proxy/firewall in between us (client)  and gateway.

Environment

Release : 9.4

Component : API GATEWAY

GMU : 1.6.00-729  

Cause

even though error in this case is pointing for possible networking issue  due to "Execution failed. Reason: Unexpected end of file from server" in our case error was misleading and issue was in encoded password 

Resolution

issue was with the encoded password. 
password that was encoded was wrong. 
so to eliminate it, please try with clear text password first.
