Hello ,
I have installed dude v6.36.4 on my computer (x86) ,
but when I try to connect as localhost he said he can’t
I have disable the firewall and also open ports 2211\2210 - and nothing
what else should I do ?
Maybe you’re using a non-standard port for winbox? Then it is necessary to use it dude.
New software builds no longer have windows server option available.
