Cannot ping or access web GUI of XG Firewall but can access console

Question

Hi All, 
 
 I have this problem where I can access our xg Firewall through console connected via micro-usb, but I can't ping the firewall nor access it through the web GUI (I know if I can't ping it, I can't access it). The only changes I made before this happened was change the ip address of the lan port. Before this change I could access it no problem. 
 When I go to network interface configuration, I can see the ip of the port that I changed. 
 I have enabled appliance access, I have changed the IP back to its original address, I have restarted numerous times but it still does not want to connect. 
 Please give me some advice.

Hi ACS IT Thank you for reaching out to the Sophos community team, After changing the IP when you access the Firewall from the machine what is the observation in tcpdump and Drop packet on XG? I hope you have already reverted the "appliance access" command which you have enabled previously, please also confirm services related to UI are not stopped/DEAD state. Please check the below RR to confirm some output and packets, and service status details: community.sophos.com/.../sophos-firewall-what-to-do-when-the-web-admin-is-not-accessible

Hi ACS, 
 We identified that issue was because of an Old Firmware running which was 18.0.4 
 We suggested to Re-image it and it resolved the issue. 
 
 Thanks for Choosing Sophos !!
