USG FLEX 100H crashing/freezing problem

Ugur

I have been using USG FLEX 100 H. It has been crashing/freezing every 3-4 days. I cannot reach/ping the firewall. DHCP stops running and wont assign any ip s. Only restarts solves the problem. I have the latest firmware. Can you please help me to solve this huge problem. Thanks

Hi @Ugur,

We found that some of the firewall freeze issue is related to the DDoS attacks. Please help to reference this FAQ to check if the solution works.
