We have a problem with logging in dashboard and administration site. We were using our accounts for a while, but since yesterday can't log in from computers in same network. We tried to log in on 3 computers connected to the same modem, so static IP adress is the same. We tried it on some computers connected to other modem too and it worked. I assume that this IP is somehow blocked or something and there is no way to log in on our computers. It says that this user doesn't exist.
Any suggestions for solving the problem?
Thank you, Zoran
