FortiGate VM GUI completely blank - white page

Hi ​@mrsmile 

if your device is in bank status that could not use Fortinet Collection tool.There are three steps they need to capture logs and a video. Thank you very much for your help.

"If creating a capture is not possible, please provide:

• 1. Screenshots or video showing the issue
• 2. Output from `diagnose debug application httpsd -1` during reproduction
• 3. Output from `diagnose debug application node -1` during reproduction "

Please feel free to share the video and logs to my email bhoang@fortinet.com ; I will check the issue and escalate to Engineering team to fix the issue as well. Thank you

Bill

Hi ​@mrsmile 

Are you able to access GUI in incognito mode?

Is this FortiGate in HA?

Is the CPU normal on the FGT?

What was the previous version?

Can you share diagnose debug crashlog read and share the snapshot of the error you are seeing

Does this occur on a new browser as well? 

As this is a new deployment, I’d suggest deleting the VM and re-deploying it.

Without valid license, it would display an error message like that:

If you don’t get this window it may be install went wrong, or this VM doesn’t have access to the Internet (interface port1 has DHCP enabled on it) . 

Can you ping from its console exe ping service.fortiguard.net, exe ping update.fortiguard.net to verify resolving and Internet availability? 

Also, execute vm-license, exe update now to re-initiate process of requesting the license. To see status of the license, namely asnwer of FOrtiguard servers if all before went OK: diagnose hardware sysinfo vm full

We are having the same problem with 7.6.7.M-build3704 on VMware ESXi. We tested it using Microsoft Edge and Mozilla Firefox. We worked around the problem by activating the license via TFTP. Link: https://docs.fortinet.com/document/fortigate-private-cloud/7.6.0/microsoft-hyper-v-administration-guide/299485

i was also facing the same issue and it got resolved by updating the license through ftp.

Thank you ​@R_B 

Hi,

you can fix the issue with web gui by configuring following:

config system global

set rest-api-key-url-query enable

end

After the license activation and the following reboot the cipher were configured to tlsv1-1, which i had to change to connect again:

config system global

 set admin-https-ssl-versions tlsv1-2
end
