Did you upgrade both RouterOS and firmware?
Can you share your config /export hide-sensitive file=anynameyoulike?
Hi, thank you for your answer.
I upgraded ROS using netinstall before I replaced the devices to the 6.48.5 version which I'm using on all my Mikrotik Devices right now. 4 days ago (I saw it right now) it was rebooted by himself giving me error which I recognize but it's not he same situation (/ip firewall connection has got about 1800 entries):
router was rebooted without proper shutdown
kernel failure in previous boot
I'm sharing you config:

One more Mikrotik sits next to it and it has no problems at all and works normally. I was trying to replace "valid one" but it still losing connection or reboot by himself as I saw right now
