APC UPS | Unable to login to APC Management

Error when trying to connect to the APC UPS management GUI (This is probably only applicable on the older models and firmware versions, but lets face it there’s a shed load of these older units gathering dust at the bottom of the rack somewhere, they get missed unless they start bleeping!)

“Someone is currently logged into the APC Management Web Server. Please try again later”

Quickest way I’ve found to resolve this is to logon to the device via telnet (Putty Client and switch to “telnet”) then exit. Simple! (Unless telnet isn’t enabled then I think it’s a manual reset from the back of the UPS unit)

Sometimes you can use the number “4” option or simple type “exit” – Log back into the Web Interface and Viola!
