Hi @Vincent-TP
For few days I was experiencing that the PC that is connected via SG2008 v4.20, firmware 4.20.20 had problems with Ethernet connection.
The Ethernet connection was up for a while and down for a longer time, then up, and down, and...
Then I passed by the switch and connected PC directly to the router. All was working normally, as usually.
I downgraded the firmware to 4.20.19, connected it back to its original position, between the PC and the router.
Over next hour all was working normally.

The issue I'm having is different. The PC I'm using to access the switch is on the same (management) VLAN as the switch itself. The web interface begins to load (shows graphics, shows the switch name in the title bar) but it either does not fully load (I can see the Omada logo, sometimes the login & password prompt shows up) or it will sometimes eventually load where I can log into it, but I can't navigate the tabs (L2 FEATURES, L3 FEATURES, etc).
Last night I was able to painstakingly get to the System Tools-->Boot Config page to roll back to "image1.bin" (1.20.21 Build 20260310 Rel.12599) which was the previous firmware. Once I did this, the issue disappeared. The version that is NOT working is 1.20.22 Build 20260313 Rel.4593.
One of the things I noticed in the changelog is "Added support for Private VLAN". I'm not sure what this means, but could it somehow be conflicting with my current 802.11Q VLANs?
The gateway issue you're describing would completely prevent / block access to the web interface - it wouldn't just load a little bit, like it did for me. I wouldn't want to specify a default gateway even if I could, because I ONLY want the management VLAN (and no other VLANs) to be able to access the web interface.
I should also note that while I was on the "bad" version (1.20.22 Build 20260313 Rel.4593) I could still continuously ping the router with 100% success, and less than 1ms of latency, and the switch config continued to function - so the connection to the switch is/was not the problem either. I simply could not load the web interface fully.

It is happening on both Microsoft Edge and Mozilla Firefox, from multiple PCs on my network. Tried clearing browser caches. The Switch appears to be functioning, however the web interface fails to fully load. The login screen loads the background, then stalls. I have tried powercycling as well, but the web interface continues to load slowly. This was not an issue in the previous firmware version 1.20.21.

@Vincent-TP For the SG3428X-M2 V1.20.21 breaks the mDNS functionality.
My Apple devices can't even see anymore the IoT devices.

Hi @Julian2111

This is the latest firmware for SG3428X-M2 1.20.24. I will update the post later. Please update it and let us know if the situation persists.
In the meantime, please try to delele the mDNS config and test again. Thanks.

@Vincent-TP I've deleted the rules and tried to update the switch, but whyever I can not update it. It says updating but after a few minutes the controller just shows "Connected", with the same firmware and says "failed to update device" without any further information.
UPDATE: The updated worked, I just needed to restart the switch before.
Whyever mDNS is still not working, I will retry later rebooting the Gateway maybe a restart fixes things.

@Spanky66 Did you reboot the switch? I had most likely the same issue.
