Can not login, but router still working

RouterOS General
1

have a Mikrotik Dude Edition that been working fine, but today my Cactus Graphs stopped working so I tried to login to the router and was not able to. It just times out after about 30 seconds and says invalid username password. Using WinBox tried to access via Neighbors but not getting a MAC address. Netfig access times out after 30 seconds.
All router function working fine. Have 2 subnets of servers and all seem to be working ok. Seems like the login authentication mechanism is screwed up on this router. Was going to reboot the box after hours.

Is it better to use the reset button on the front of the box to restart or unplug both power plugs for a few seconds. I thought the reset button was for restoring default config if you hold the reset button in when powering up, but not sure if it will do a reboot just by pressing and letting go the reset button. Afraid to wipe out my my config so I thought I would ask the best way to reboot the router. Usually do it from within WinBox but not, able to right now.

Thanks

There’s been a few reports of this with the RB1100AHx4 routers. Have you tried Webfig to get in as well? Pulling the power is ok.
Make a Supout.rif and submit a ticket to Mikrotik once it’s rebooted.

Was able to reboot the Dude and get logins again. Seeing a lot of ppp attempts at about when the problem started.

Not using ppp or VPN’s right now. What port(s) do I block or how to stop anyone trying to log into my ppp ports. Might be the attacks are causing the login auth mechanism to get locked up.
Would like the ppp to appear nonexistant.

Thanks!

Blocked GRE and UDP connection 500 in forward chain which should block incoming VPN
