HTTP-Proxy not working (Windows)

Question

Hi Guys, 
 
 I'm new to the Sophos Firewall, but I have some experiance with other Firewalls. I set up a new Sophos XG Home Edition and it's doing the job very well. 
 
 I just have a problem and hope you can help me to solve it. I'm using a HTTP-Proxy which is, for example, configured in Internet Explorer. It's working as it should, but since I installed the XG Firewall, the HTTP Proxy is not able to connect (get no dialogue to type in the credentials + no website can be opened) and so it's not working. 
 
 The only thing I have configured is a Firewall rule source/destination/service set to any, to have no restrictions. This rule doesn't use and application or web filtering. The Sophos log shows an entry form my pc to the http-proxy-IP with the port 443 and it's accepted due to the firewall rule. 
 
 So I have no reference point what could be the problem. A friend also have a http proxy and there it's working, but he uses UTM Firewall. Any suggestions would be appriciated. 
 
 best regards

Hi Benjamin, 
 When the website has terminated the connection, the XG would remove the state-full connection with the remote web server. If the packets are received after the connection was terminated then the packets are invalid packets. As per the packets captured the connection is already terminated and the finished packet is an invalid packet afterward.

Hi Benjamin, 
 Could you check any irregular logs in XG under awarrenhttp . 
 The command in shell 
 #service awarrenhttp:debug -ds nosync {this command will enable debug mode for service enable/disable to disable execute the command again} 
 # tail -f /log/awarrenhttp.log 
 Post your output and then disable the debugging mode.
