Login Weather34 Settings does not work

[Gocher66]

Hello,
I have setup weather34 in my Nano SD and it work as expected. I went to the dashboard and I was able to see that I can make some adjustments in the settings option. I signed in with my meteobridge password and access was possible.

Then I tried to enter this the second time, but it does not work anymore.
I have not change password or anything else. The web page stucks always at the login page and comes back to the Login screen. The URL is xxx.xxx.xxx.xxx/PWS/easyweathersetup.php, where x is the ip of the Nano SD.
So can someone give me tip, what I have to do to get access to the settings again?
Thanks in advance

Found the answer .

First time you login, you have to use the meteobridge password.
Then you have to change it. This is in my point of view not shown so well. If the password is not change, it will be a blank password, for all future accesses until it will be change
