KeyError: ('127.0.0.1', 58365) in greenlet.py line 766 > lib/gevent/baseserver.py line 26 > ... > core/src/Ui/UiServer.py line 72

### Step 1: Please describe your environment

* ZeroNet version: 4455
* Operating system: W10
* Web browser: FF beta
* Tor status: available
* Opened port: no

### Step 2: Describe the problem:

error in the debug.log:

> ERROR - Unhandled exception: KeyError: ('127.0.0.1', 58365) in greenlet.py line 766 > lib/gevent/baseserver.py line 26 > ... > core/src/Ui/UiServer.py line 72

Start by tracing the reported exception from greenlet.py line 766 through lib/gevent/baseserver.py line 26 to core/src/Ui/UiServer.py line 72. Reproduce or isolate the KeyError for the reported localhost address and port, then verify the server no longer logs an unhandled exception; the issue provides no test or explicit expected behavior.
