I just got my new hAP ac2, however I have the problem that I can't log in via WebFig. When I open the login page and enter the username "admin" and a blank password, I get the message "Authentication failed: invalid username or password.". Interestingly enough, login via Telnet with the same credentials works fine. I've already tried a factory reset, but as it seems, that doesn't affect the users configuration and passwords, so that didn't help.
What do I have to do to access WebFig? Is there any way to reset the admin password, or do I have to activate access to WebFig somehow...?
RouterOS version is 6.40.5.
