Trouble with firewall policys

[CVB1]

Good morning, I have a forti 60F and for a few days I have been experiencing problems with the firewall policies, they worked well and now I have to create groups without any security profile so that they can access the internet, the problems are permanent, could you help me try to discover what's going on?

Firmware: v7.0.12 build0523 (Mature)

Another thing I noticed is that even though dhcp assigned me an IP to a machine, on devices it still shows me the old IP.

An the CLi Console shows me connection lost.

Thank you so much

Is there any resource issue with your FortiGate?
If you check with 
diag deb crashlog read 
Do you see any process being killed or memory conserve mode?

I can't access cli console.

Connection lost. Press Enter to start a new session.

I was able to get it out by logging in via ssh.

For your CLI from GUI, you can follow this guide and it may do the trick:

For the second issue it seems like you have had some problems with WAD that would impact traffic if any security profiles are activated.

Try to open a support ticket to follow WAD , or upgrade to another FortiOS version, from which i would recommend 7.2.6 or 7.4.1

Can I go from 7.0.12 to 7.41 without installing any other intermediate version?

Hi @CVB1, 

Unfortunately, you will need to go to 7.2.6 and then 7.4.1. Please refer to the following for upgrade path "https://docs.fortinet.com/upgrade-tool"

Hi @CVB1,
The fact that you need to create another policy without security profiles to access Internet means that your UTM is blocking traffic. Can you please check under security events logs to see what is blocking traffic?
