Firebase Hosted flutter app shows not a secure connection error when launching an external URL

Question

When I open my Website hosted by Firebase Hosting Google Chrome or my Antivirus program does not let me access the page but shows me an error message:

This is not a secure connection. Hackers might try to steal your data from (website), for example, passwords, messages or credit card details. Error code: NET::ERR_CERT_COMMON_NAME_INVALID

Any Ideas?

Solution

I solved it! I just had to exclude the www. in the url_launcher String and it will not display any SSL-Error.

It's SSL certificate related, adding your index file or providing the website address will be useful.

I have checked it on Safari, Chrome, Firefox, and Brave works perfectly no cert issues.

Oh yeah, you are right, thank you. But I found another Problem :( . If I use it with Flutter Plugin url_launcher and launch my website with launchUrl() I got the described problem.

[Hooshyar]

Overall the issue is not related to flutter, it is related to SSL configuration, what is the URL of the website you are trying to launch?

[Cubii]

It's the same link as above. When you copy-paste nothing happens. But when you launch website in flutter-app with url_launcher package then this problem occures. On all links that are with my website address

@Hooshyar where do I have to look for the index file? I still got no solution for the problem, because like this I can't use my Firebase hosted website like I want.

[Hooshyar]

I’ll check and let you know

I solved it! I just had to miss out the www. in the url_launcher. But thank you very much @Hooshyar
