Hi,

GLib Version: 2.62.0

Im seeing in my client that 5 times out of 10 the proxy set via SocketClient.set_proxy_resolver() is simply ignored without any error whatsoever, and SocketClient just connects to the destination address without proxy.

I would consider this a big privacy/security issue.

Maybe someone can try to reproduce this themself

from my application logs it looks like this

I made sure that proxy-enabled is set, and made sure the SimpleProxyResolver object is set on the SocketClient, before and after connecting to the server.

I happy to provide more info if needed
