@forrest The internet connection is "stable" and reliable, so I'm inclined to rule that out. (fwiw it's not a OC200 but the omada software controller)

Maybe relevant (maybe not): The internet connection is (unfortunately) via DS-Lite (unitymedia), i.e. the router has a public IPv6 address and a shared IPv4 address.

I'm running the Omada Controller Software 3.2.6. When Cloud access is enabled, I get the following error every 4 minutes in my server.log: 2020-03-21 01:38:34 [Thread-14029] [INFO]-[SourceFile:913] -...

I use the software controller (3.2.6) and EAP225-Outdoor(EU) 1.0 : 1.7.0 Build 20200113 Rel. 35383 EAP245(EU) 3.0 : 2.4.0 Build 20200117 Rel. 39932

Seems I can reproduce this issue. I've never seen this before, but I've upgraded the firmware of my 245v3 and 225v1-Outdoor over the weekend to the latest available version. Now I see clients still...
