I updated my cloud controller to version 5.0.29 and after the update i restarted my browser and entered page  https://omada.tplinkcloud.com/#controller   i could not see my controller... weird no controllers found, i refreshed my browser multiple times but nothing....in the end after not finding any other solution and after not finding my backup (which i now have and it's safe LOL)  i setup everything from the beginning....the controller setup from scratch entering device key to recognize the device etc, after this i launch it  and i see no wifi hotspots, settings lost and the eap's "managed by other...."  so i reset each access point with reset button and i adopted then one by one and created new wifi hotspot and voucher codes...i did the entire job like i bought them new. 

Dont know what the heck went wrong there....

What was the uptime on the controller?

For safety sake, I reboot one of my controllers that was running 250days before updating. No Problems.

Also, I updated about 4 or 5 additional controllers at customer sites with less uptime without rebooting, no issues.

I know I had some issues upgrading router firmware last year and one recommendation was to reboot before pushing update if possible.

@EIBROG 

No idea about the uptime @EIBROG !

I remember i had a reboot schedule for every Sunday but im not sure if this reboot was for the controller or for the access points. I will keep your reboot tip before update for some other time

Ever since the firmware update I'm seeing the same error.  And even after following the instructions on archiving the logs and cleaning the logs, in less than an hour I see the same "The number of logs is up to the limit"  alert.

I think there are lots of bugs in omada v5.0.29

1) after forget omada eap 225-outdoor from software controller acess point didn't reset ( eap 225-outdoor still broadcasting same ssid and using same static ip ) and i am not able readopt when I tried,  username and password was needed and for admin/admin it showing incorrect password.

since this eap225-outdoor placed outside on top of a pole i need to manually reset and it is bit difficult for me to do it, for this kind of software bugs.

2)the reason why I tried to forget is the another bugs eap225-outdoor always hearbreath missing for this reason I tried to reset.

3)then logs

I'm having this issue with logs too. Why can't we manually set the log limit? Also, it's happening even with all logs archived.

The folder " ../work/omada-web/webapp/WEB-INF/omada/static/" for a file printVoucher.html, very important for customizing the printing of vouchers? Please TP-LINK people advised what happen? how can I edit it?
