We have a PS4100E which is no longer accepting connections to the web interface, nor to remote SSH or telnet. The only way I can access it is via terminal cable to the CLI.

How can I get the web interface back up and running? I've already tried

grpparams webaccess enable

but this makes no difference. I don't have the luxury of being able to do a full restart of the unit at the moment. Is there a way to get it back up and running?

Thanks in advance.
