It looks like Matt's latest changes, which where supposed to fix mod_unsafe_compression on prosdody 0.10 (thanks for that), are not complete. Here is an XMPP trace from MAXS trying to enable compression after authentication: 10-14 15:29:34.258 D/MAXS/XMPPTCPConnection(30584): Established TCP connection to /37.221.197.223 at port 5222 10-14 15:29:34.264 D/MAXS/JulDebugger(30584): SENT (3): <stream:stream xmlns='jabber:client' to='geekplace.eu' xmlns:stream='http://etherx.jabber.org/streams' version='1.0' from='flo-motog4@geekplace.eu' xml:lang='en'> 10-14 15:29:34.359 D/MAXS/JulDebugger(30584): RECV (3): <?xml version='1.0'?><stream:stream xmlns:stream='http://etherx.jabber.org/streams' xml:lang='en' from='geekplace.eu' id='a10586bb-8afe-4df3-a6fe-7ad505130dcf' version='1.0' xmlns='jabber:client'><stream:features><mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'><mechanism>SCRAM-SHA-1</mechanism></mechanisms><starttls xmlns='urn:ietf:params:xml:ns:xmpp-tls'/></stream:features> 10-14 15:29:34.361 D/MAXS/JulDebugger(30584): SENT (3): <starttls xmlns='urn:ietf:params:xml:ns:xmpp-tls'></starttls> 10-14 15:29:34.416 D/MAXS/JulDebugger(30584): RECV (3): <proceed xmlns='urn:ietf:params:xml:ns:xmpp-tls'/> 10-14 15:29:34.898 D/MAXS/MemorizingTrustManager(30584): checkCertTrusted([Lcom.android.org.conscrypt.OpenSSLX509Certificate;@74a6584, DHE_RSA, true) 10-14 15:29:34.898 D/MAXS/MemorizingTrustManager(30584): checkCertTrusted: trying appTrustManager 10-14 15:29:34.909 D/MAXS/MemorizingTrustManager(30584): checkCertTrusted: appTrustManager did not verify certificate.
