Is there any easy way how to check for internet connection ?I tried to use HTTPRequest node but with no luck (some ssl problems).Is there any easy way how to check network availability without owning server or certificates ? Thanks. -Garrom

As far as I know, Godot does not expose a way to check for Internet connectivity using OS APIs. As a workaround, you could try requesting a page from a public web server such as example.com (which is a domain reserved by IANA, so it should always be there).

Thanks, I did not known about example.com. However, when I try it in log is Cause: unable to get local issuer certificate [4, 0, [], [PoolByteArray]] #caused by printing the result of "yield($web,"request_completed")"

In debugger are two errors.

0:00:01:0217 - Some I/O error occurred. The OpenSSL error queue may contain more information on the error. Type:Error Description: Time: 0:00:01:0217 C Error: Some I/O error occurred. The OpenSSL error queue may contain more information on the error. C Source: modules/openssl/stream_peer_openssl.cpp:429 C Function: _print_error

0:00:01:0222 - A failure in the SSL library occurred, usually a protocol error. Type:Error Description: Time: 0:00:01:0222 C Error: A failure in the SSL library occurred, usually a protocol error. C Source: modules/openssl/stream_peer_openssl.cpp:432 C Function: _print_error

Btw. It referring to protocols, Do I need them ? If yes, where I can get them ?

When running a project using a non-editor binary (i.e. an exported project), you should configure the path to a certificate bundle in the Project Settings (Network -> Ssl -> Certificates). You can use the same one as Godot, which you can download from here (save it as a file). Note that starting from Godot 3.1, SSL certificates will be bundled with exported projects so you will no longer have to do this.

Alternatively, you could request http://example.com in plain HTTP mode. If you're only checking for Internet connectivity, it should not be an issue.

That certificate done the tricks, Thank you a lot !

I just realized DNS isn't going to work without an Internet connection… Try requesting a page from an IP address such as 1.1.1.1 instead.
