Invalid Administrator username or password. Error code (1722)

Hi everybody, my name is Piero, from Florence (Italy)

I am having a connection problem (Invalid Administrator username or password. Error code (1722)) trying to connect via Logmein Tech Console (v. 7.12.3306 64 bit) from my pc to a host pc on a different domain.

When I receveid the connection dialog to insert user&password, i try to use a local admin user of the host pc but i received:

[2018-05-10 4:24:28 PM] Starting session on device 10.20.35.21...
[2018-05-10 4:25:27 PM] Invalid Administrator username or password. Error code (1722)

The user&password of the remore pc is correct, so i tried to do the same starting from a different pc (with same version of Logmein Tech Console) which is in the same domain of the host pc and this time it works, i can connect inserting user&password (as done before)

Tried with and witout proxy settings (just to be sure).

Did you get any cross domain connection error like this in your Logmein usage?

Thanks

Piero
