@Fae 

Hi, i've upgraded from 4.4.6 to the 5.0.15 beta and it crashed my installation.

5.0.15 failed to upgrade the database. Even after a reboot of my Windows Server 2019 the error still occured.

I had to deinstall 5.0.15 clean the install folder contents and reinstalled 4.4.6 with a following restore of my backup to have the Omada Controller software running again.

FYI:

The Omada Software was not installed in its standardfolders on my server!

 

Best regards.

Sorry to hear that you have trouble with the 5.0.15 beta.

I tried to upgrade from 4.4.6 to the 5.0.15 beta and it goes well.

 

To address the issue, I'd like to escalate your case to the TP-Link support team for further investigation.
They will reach you via your registered email address shortly, please pay attention to your email box later.

 

Thank you so much for your cooperation and support!

Thank you for your valued feedback.

 

There will be a fix for the local Omada Controller v3.2.14 also, I'll update the solution once the firmware is available.

 

BTW, is your Omada 3.2.14 installed on an Ubuntu-machine as well, or is it a hardware controller?

 

Update:  The beta firmware for Controller v3.2.14 has been provided, please follow the solution above. Thank you!

Installed beta 5.0.15 (software controller om windows) updated without problems but Omada android app displays an "Omada server error" when opened.

App seems to work ok

 

The same with Omada cloud web page and controller webpage but here an "general error". Also the page seems to work ok.

 

 

 

Kind Regards

Peter

@PeterHor 

 

I do not understand why v 5.0.15 has not been removed from the download, this version has bugs, this has been known from day 1, I have been in contact with tp-link support about this error and they promised a fix in November but this has not happened yet.

 

Look at this post,

@shberge 

 

When i moved to 5.0.15 before log4j patch, my APs wouldn't connect and i also had that generic error.

 

Sadly the one time i didn't create a backup was the time i actually needed it.

 

I had to rebuild everything which not fun but is fine as my database was from the old non SDN controller and had problems. Since rebuilding 5.0.15 has been working good.
