This most probably means that the "serverip" which does not get substituted is not the "serverip" you tink it is, i. e. eventually it contains some non-printing characters or control sequences. I recommend to re-enter the complete variable definition. Do not copy & paste, but re-type it from scratch. Then test again. You can also run "md" on the sector where your environment is stored, and check what's actually stored there.
