Sophos firewall GUI not accessing

Hello BilalAmjad ,

Thank you for reaching out to the community, may we know the current firmware your appliance is running on ? 
Please try referring the steps mentioned in the following KBA_Sophos Firewall: Unable to access the GUI.

Hi Vivek, 

It's v19.5 and I already followed the Referred KBA.

Hi BilalAmjad ,  can you share the tcpdump output and logs as mentioned in the KBA above...

check the logs and output detail 

Hello there,

Adding to what Vivek mentioned.

If the issue persists, please open a case with Support and share the Case ID with us.

If you have gone trough the KB, probably an issue with the database or HDD.

Regards,
