Just upgraded our test environment to the latest version 5.3.0, admin GUI access was previously ok via Port1. After upgrade can't login, tried the "restore-admin" cli command as I am still able to login to the server as admin, any thoughts? I upgraded from version 5.2.2
is it possible that you are trying to reach the appliance behind a NAT?
maybe the IP address that you are trying to reach is not under the:
Administration > System Access > Additional allowed hosts/domain names:
Yeah I did think that could of been a cause but was this setting also in 5.2.2 as I could login fine from the same locations on that version. Also, how would you add your host/domain name to that allowed list if you can't access the GUI?
