ConBee II - Random connection issues

I’ve been using a ConBee II stick since last spring without any issues what so ever until a few weeks ago.
I have a few Hue motion sensors & remotes and two Ikea dimmer switches connected to it, all of a sudden I noticed the motion sensors were slow and sometime didn’t even trigger and after a while I saw they had a red led shining so I looked that up. Turned out the red led indicated connection issues with the bridge.

I’m not sure why this issue arise all of a sudden, but I sure would like to solve it. Has anyone one experience anything similar before? Where should i start looking?
(I’ve tried changing ZigBee channel without any improvements)
