blaine07 I'm not sure.
I didn't change any settings (haven't in at least 30+ days). Update to 6.0.20 went fine, although there was a dialogue about "some network settings are not compatible with this version (but couldn't find anything specific that was marked as not supported, and I'm not doing anything that would be unsupported or sneaky). Then the 6.0.22 update killed all connections to my WiFi devices.
Some details:
2 VLANs
2 Wireless networks with 3 SSIDs (one for computers, and two for the IoT VLAN so they stay on the appropriate AP)
Basic routing and firewall rules for IoT setup
Ethernet connected devices were not affected at all. Full throughput, fully accessible, no errors / issues
Rolled it back in Docker to 5.14.23-ls76, uploaded my backup from that version and all is right in the world again
Any suggestions on how to avoid this would be appreciated; I can upload screenshots but like I said I'm back on 5.14 for the foreseeable future
