RB 1100AHx4 is not working

Good afternoon!

Router model RB 1100AHx4

It started to hang (links are not lit, it does not ping, it is not available via Winbox and SSH), only a reboot helps.

I flashed it via NetInstall to version 6.49.2 Stable

We set up a simple configuration for accessing the Internet and several port forwarding, but this did not change the situation.

Can you tell me, please, what the hang ups may be related to?

Are you referring to a constant boot loop or some random reboots ?

With ROS 6.49.0 is working perfect. I’m running one.

Regards.
