Hello,

You may consider to connect to the unit over the console and follow the steps below:

Check routing table:
get router info routing-table all

Sniff the traffic:
diagnose sniffer packet any 'host <filter IP address>' 4 0 a

Collect debug flow:
diagnose debug flow filter daddr <filter IP address>
diagnose debug flow show function-name enable
diagnose debug flow trace start 100
diagnose debug enable

Hi @Vladimir_VM,

Are you able to ping 192.168.1.99? I also believe that 200E does not have any reset button. Maybe try to access using console or SSH instead of HTTPS.

Please take the console access of Fortigate, any console cable will work.
Check the IP address on the mgmt interface and allow access,

# config system interface
# edit mgmt
# show

Make sure the IP and subnet are correct and "allowaccess" to HTTP, HTTPS, ping, and SSH.

Test the connectivity with ping, and make sure the pings are working.

If the pings are good that means the connectivity is perfect!

Later check the https port that has been used, (the default is 443).

# config system global
# set admin-sport

Another thing that needs to be taken care of is the certificate,
Please make sure either Fortinet_Factory or self-signed cert should be applied below.
config sys global
set admin-server-cert
end
