Can't connect to RB750 after power cycle

RouterOS General
1

Hey folks,
I’m a Mikrotik newbie, and I’ve had some odd behaviour with my RB750. I’ve found that if I have to power cycle it, I can no longer access the configuration for the router, either through the web interface or winbox. Connecting via MAC or IP address in winbox both yield the following error: “ERROR: Cannot connect to..”.

Internet access and VLANS appear to work regardless. The only way I found to get back into the router was to do a reset of the configuration, which is tiresome to say the least, and there are more tweaks that need to be made.

Any help would be appreciated!

Have you tried to access by its mac address (64:D1:54:B1:DF:A2) instead of trying the IP address (192.168.3.1)

Clear cache from the menu, make sure your computer has the other interfaces turned off (like wireless etc.), try to reboot, try the MAC address.

I had already tried connecting via the MAC (see my original post). Clearing the cache, and even trying it from other computers on the network have all yielded the same results. Still can’t connect to it.

Any other ideas? I don’t fancy the idea of having to redo the configuration every time I want to make a change.

Quick update, I did a full reset again, and I can now connect with Winbox via MAC address only. It’s entirely possible that, with my VLAN setup, I’ve somehow cut myself off from accessing the interface via IP, but I’m not sure what I would have done that blocked it.

Here are my firewall rules. I am on VLAN 1. Is there anything amiss here that I could’ve misconfigured? If you need to see any more information, let me know.
