When I log in to the SN unit from web browser (No matter what) and Press on "port Access" I got error message - "Parse update message error"

If it connects to the SN through SSH (not browser) ， the connection is OK， and I can enter the ports on the SN.  How to fix the issue?

SN supports below characters on port/device name only and you may have filled in character other than them from telnet/ssh: 0-9 a-z A-Z . _ - ( ) [ ] and space.

Please refere to attachment to modify and fix the issue.
