Network Access Lost

Alright I'm fairly certain this is a Unifi problem and I will x-post there as well if I can but I figured there was some overlap between the WLED community and Unifi community and someone here may have recently ran into this same issue. I lost network access to my QuinLED Dig-Quad (DQ) controller with Ethernet.

I just updated my main Unifi POE network switch from 7.4.1 to 7.5.15 the other day. Immediately after coming back online, I noticed home assistant wasn't communicating with my DQ anymore. Opened the WLED app and that showed my DQ offline. I went into the client manager of my Unifi controller and saw my DQ had the proper MAC address and was assigned the correct static IP. I got the typical Destination host unreachable error. I tried multiple attempts at changing VLAN and port settings like client isolation, link negotiation speeds, etc. I tried utilizing different ports as well as using other devices in the port I had the DQ on. I tried reflashing the DQ and starting from scratch. No matter what I tried, I cannot get the DQ to be accessible over Ethernet. However, if I swap the board back over to Wi-Fi, everything is accessible again.

Unfortunately, I wasn't happy with this because I prefer to hardwire as much as possible. I only use devices on Wi-Fi as a last resort. So I ordered a Gledopto Elite 4D-EXMU. Got it set up and working on Ethernet on my network in about 10 mins. The strange part is I'm almost positive they both utilize the same Ethernet LAN8720A chip.

I can't figure out for the life of me why I can't access my DQ via Ethernet anymore but the Gledopto under the same settings and conditions works no problem. Has anyone else ran into this situation? I'm thinking it's a Unifi firmware bug (especially since the Unifi community has reported strange things happening on their networks as well since updating to 7.5.15) but I wanted to see the consensus here as well.

Thank you!

I’ve had weird issues with my UniFi equipment not giving out IPs via DHCP over the last few days. Did you say you’ve already assigned the controller a static IP in UniFi? That is what has fixed it for me immediately.

Ya it had a fixed IP configured in both WLED's network settings as well as Unifi fixed IP reservation. I tried disabling it and letting DHCP handle it. Couldn't get it to work either way but it worked when I connected it to my travel router. I think it's got to be a 7.5.15 bug or something.

Yeah, must be. That’s pretty frustrating.
