Web UI very slow after modification to DNS settings
Using our new ATP200 was fine until I modified DNS settings (added one public DNS service 1.1.1.1). Since applying this modification the web UI became very slow, and now it's unusable. Login takes minutes, and then the UI does not show. Any idea?

Hi @Stefanoco
Welcome to the forum.
I suggest you provide more information to help you: firmware version, network traces, event logs ...

Hi @Stefanoco
Welcome to Zyxel Community 😀
Can you post the screenshot of your DNS settings?
Also, when the Web GUI became slow, what is the result of CLI “show cpu average”?
CLI: show cpu average

Hi thanks for answering. Pls find below the DNS setup and hw/fw revision page. Regarding the other data, I must tell that this morning there was a reboot of the firewall and now access to web UI is normal, no more issues. So it might be a glitch due to saving the new configuration. My only concern is that this happens again during modifications. What's your opinion?

Will the issue come again if you delete the DNS 1.1.1.1, and add it back again? 😅

Not sure that I want to try this worktime, perhaps during the weekend...

Hi @Stefanoco
Maybe I can help you to test it.😀
Can you send me your configuration via private message.

Hi @Zyxel_Cooldia sorry can't share the detailed configuration for security reasons but it seems working correctly for the moment.

Hi @Stefanoco, okay, let me know if you encounter any issue.😀

Hi @Zyxel_Cooldia following a few days of observation, I realized now that the Web UI gets very slow down to not responding after a few days of uptime. It seems to me that this is not related to any specific setup but I may be wrong. Reboot solves, and appears again after days. Of course I can't debug while not working unless I connect the console cable.

Sorry @Zyxel_Cooldia I realized now that I also have SSH access enabled from our LAN so here's the CPU load, any other information you may need from CLI ?
