FortiOS 7.4.7

Hi,

Strange behavior happened after upgrade from 7.2.10 to 7.4.7.Whole Company started to lose connectivity both to Internet and internal resources. We rebooted the device and it resolved the issue for like 30 minutes and started doing the same behaviour. No major changes since yesterday whatsoever.

It was upgraded during last weekend, but the problems started to occur this morning. For now, firmware was downgraded to 7.2.10 and it is stable again. Any of you had this issue?

Regards
