I'd expect TLS connection to conversations.im to succeed

Socket error code: 24 [CertificateUntrustedRoot]
Error message: TLS upgrade failed after 68.5984 ms with: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. (Exception from HRESULT: 0x800B0109)

Thanks for reporting this.
To me this does not look like something I can actively fix since I'm using the default WinSSL certificate chain for UWPX without any changes. To further diagnose this I have a couple of questions:

• Did you change anything on your certificates in Windows?
• Are you able to connect with other clients (Gajim, etc.) from the same PC to conversations.im?
• Is the connection running through any kind of Proxy/VPN/... ?

I will try to create an account at conversations.im to further diagnose this my self.

In the meantime if you are sure, nobody is manipulating or intercepting your connection, you can disable this type of TLS cert. validation in the UWPX settings:

Hi Fabian, many thanks for your kind reply! Disabling the TSL verification solved the connection issue, I just missed the option in the setup - sorry! To your questions: * Did you change anything on your certificates in Windows? No * Are you able to connect with other clients (Gajim, etc.) from the same PC to conversations.im? Yes, but only by disabling certificate validation * Is the connection running through any kind of Proxy/VPN/... ? No, simple cable-based home internet connection All the best: Chris

Sadly I can not reproduce this one.
Is it still not working for you?
