DisableNetwork is not unset if bootstrapping fails
Reloading TB's Tor instance disables network and keeps it turned off because it fails to attach to the SocksPort. One has to change the SocksPort, enable the network and change back the SocksPort with nyx:
>>> signal reload
250 OK
>>> getconf disablenetwork
250 DisableNetwork=1
>>> setconf disablenetwork=0
553 Unable to set option: Failed to bind one of the listener ports.
>>> setconf socksport=9152
250 OK
>>> setconf disablenetwork=0
250 OK
>>> setconf socksport=9150
250 OK
