Server stops after a login failed try

David_Tinajero

Hi again moohoo friends.
I’ve installed MailCow in a cloud instance using a 2 cores AMD processor with 8GB RAM and 128GB SSD, it is working fine.
This until I try to login to the server and I make a mistake.
A t first try the server stops to work, I can’t recieve or send messages, and when I look for the administration tool, the page is fallen.

I hope someone knows something about this issue.

Thank you so much for your help.

I’m running on Linux, the problem is that I can’t connect to my instance, it seems averything stops, the ports does not work, this include the port 22.
I have to reboot in order to restablish the service, after that everything works fine.

David_Tinajero I guess that fail2ban is blocking your IP upon a failed login. But the default setting is 10 failed logins.
You can whitelist your IP

DocFraggle Sorry I forgot to answer.
It could be, I didn’t know Fail2Ban does that, then, I have to test, but i think it could be te reason.

Thank you for your help… Again.
