Hallo,

is the client working normally in between?
the log says that there is an issue with the HSTS validation of QT.
Is there anything helpful in the debug log of the client?

[zsoltbarat]

Yes the client is working normally and yes it seems a HSTS issue. I had initially set HSTS max age to 10 minutes for testing. But I´ve upped it now to 1 week. deleted HSTS cache for the client locally. No crashes so far, probably in a few days then :).

[wvolz]

I'm having this same issue with client 4.0.6 and my HSTS max-age is set to 300. Before I change it on the server side, do you want any additional logs?
