Hi,

Hi,

L+G G405 is new meter to me, but your meter returns authentication failure. Is your password correct? Can you connect without authentication?

Hi,

Hi,

If you can connect without authentication there are two possibilities.

1. Password is wrong.
2. client address is wrong.

Check the password first. Someone may have changed it.

BR,
Mikko
