Can't connect via browser to 3500yl (has worked previously)

[WB-Support]

Hi

The switch has been up for 205 days with no issues. 

I went in via a web browser today and am just getting a timeout issue (see screenshot).

I have tried different PCs and browsers.

Telnet and console cable are still live.

I was wondering if there is a command I can run to reset something to allow me on. I see in the manual there is a 'web-management' command, but my switch doesn't have it. The config 

I don't want to reboot it, but may have to as I can't see a fix. K.12.84

Any ideas please?

Hi

I'm sorry but you don't really have other possibilities but rebooting. Either use Reset button, or reload -command on the CLI. After that I'd suggest you consider upgrading. On that old version you will need to go first to K.13.68, then you can go to current firmware. Since you're apparently not using the new features of K.15 -branch and aren't updating too often, I'd recommend m-version (maintenance release). Current one is K.15.04.0018m.
