Can you try switching a browser? For example, when using the Edge browser, in most cases it is because of cache or cookies.

Change on both ends of the IPsec tunnel, on the Firewall Policies for the IPsec tunnel, the "tcp-mss-sender" and "tcp-mss-receiver" to 1350, using below commands:

On FortiGate-1 and FortiGate-2:

config firewall policy
edit <policy id>
set tcp-mss-sender 1350

set tcp-mss-receiver 1350

next
end

Hi @grico,

When you say GUI is not working, could you let us know if you are getting any error or warnings? If yes, could you help us with a screenshot. Also, please confirm if the CLI access works fine.

Regards,

Vimala
