Thank you for reporting! Is that error (also) occurring on the main branch? Or only in #75?

[Ifilehk]

Yes problem in main branch there too

[JKRhb]

Yes problem in main branch there too

Hmm, okay, can you determine where in the code the error occurs?

[Ifilehk]

will troubleshoot

[JKRhb]

Thank you! I already have an idea for a fix, I will push it later today

[Ifilehk]

Danke!

[JKRhb]

Hi @Ifilehk, sorry for the delay! I now updated #75 with a potential, very simple fix (commit aa448c8554eb3e5b5f487057e76f701863bdcceb), could you try it out again? :)

[Ifilehk]

Now crash occurs at line 477 in dtls_client.dart

final code = _libSsl.SSL_get_error(_ssl, ret);

[JKRhb]

Thank you again for the feedback! I updated #75 again, could you try once more with the latest changes?

[Ifilehk]

You got it!!! Parabéns!!!

Danke!

[JKRhb]

Great! 🎉 Thank you again for your testing effort! :) (Muito obrigado! ;))

[Ifilehk]

De nada !!!

[JKRhb]

De nada !!!

🎉

I will publish a new patch version later today by the way :)
