Navigraph charts keeps logging out

Hello, I have an issue with my navigraph charts app on windows.
Starting this morning, my navigraph charts suddenly logs out of my normal account. And I have to log back in. But then I’m still able to logged back in normally. But every time I closed the app, and opened it again, it logs me back out.
Now when i opens the app and click log in, it doesn’t opens up the log in tab on my browser.
Right now I’m using Opera Gx as my default browser, Any help would be appreciated. Thanks!
