Lost traffic after upgrade

[stevenp]

I completed an update for fortigate VM to 6.4.7. which worked fine. However, it knocked out a policy for HAproxy which caused an outage of our applications through http and https.

Its seems that all traffic is getting dropped at HAproxy.

I rolled back to the previous software version and found it was still the same. But once I put the back up config file on, all applications fired back up.

Is there a security feature or new feature in the config causing the issue I had??

Hello Steven,

Could we please ask you to update to the newest revision 7.2.

It could fix this issue.
