<p dir="auto">I saw about 15 out of the 60 requests return <code>Error performing TLS handshake: An unexpected TLS packet was received</code> when I just ran it.</p>
<p dir="auto">I'll try to strip it down from there on another night. I had to put the proxy creation in the loop so that it didn't keep re-using the connection. I suspect other background tasks are consuming the connection pool in the app, which is why I saw different behaviour when reusing the proxy (as the app does).</p>
