I have a wierd problem with Winbox logging to one RB450G: Winbox hangs on connection attempt, showing "Retrieving preferences ....". After some time it reports "Router has been disconnected".
I have checked and found many suggestions, all pointing to damaged plugin or something similar, but the reason must lie somewhere else. Here are the facts:
Chaniging Winbox version only generated the fault in a different phase of login.
Changing router OS from 4.11 to 5.4 did not change a thing.
Any version of Winbox on that very machine can login to 20 different other routers I have access to.
If I VPN to my company LAN, I am suddenly able to login to the router with very same Winbox(es) that did not work before.
Does anyone have any idea where to look?
