That's not a valid license key.


Just bought a starter license to use with my Confluence installation.

Yet, when I copy/paste the license, it says "That's not a valid license key.".

How can I fix that?

Hello Cédric,

I was able to get in touch with our Advocates team, and I see they had manually provided you with the license. 

Before we proceed, I would recommend first pasting the license key into a text editor that uses plain text, such as Notepad. Then you can copy the license again from that application.

Sometimes a space that is copied is invisible, so you wouldn't see it when copying it yourself. 

Can you give that a try and let us know if you still have any issues? I've had the Advocate verify the license is valid and has valid maintenance, so we just need to narrow down why it might be still failing.

Kind Regards,

Hello Shannon,

Thanks for your reply.

I copied/pasted in a text editor (sublime text), then copied/pasted from there to the page and get the same result.

Here are some technical information that might be helpful for diagnosis.

I am using the Confluence docker image (, running on a Synology NAS.

I am accessing it through a HTTP reverse proxy.

The NAS has access to the internet (no proxy).

Our licenses do not require an Internet connection, as they don't "call home" like some licenses. Your proxy shouldn't be garbling the license.

I applied the license from your support ticket with our customer advocates team and it worked fine on my test instance.

For troubleshooting, please try generating an evaluation license at and checking whether that will work.

Hi Ann,

Thank you.

The evaluation license also didn't work.

I recreated the container and now it goes through license validation.

I have no idea what went wrong.

Thank you all very much for your time.

My pleasure, I wish I could have been of more help. I also wish we knew what happened on that first container but I suppose there are mysteries even in technology.

Thanks for letting us know how you fixed it.

By the way, if anyone gets a nginx gateway timeout during the external database configuration, the reverse proxy is the cause.

I had to disable it.

Good to know, thank you!

Check that you have copied the whole key, and just the key - no extra spaces or tabs at the beginning or end

I copied the whole key, without spaces nor tabs at beginning and end, and still have the same problem...

I tried on two different browsers (Chrome macOS and Safari macOS)

The key has 77 characters on the first line, 76 on the next 5 lines and 48 characters on the last one.

I tried to see if it was a valid base64 string, which it is not.

I tried to contact Atlassian support but they asked me to ask for support here instead.

I am completely stuck with an invalid license which I cannot use...

Hello , I wonder  how you fixed it ? 

Because I have same issue right now .

Thank you 


I basically reinstalled in a new VM if I remember correctly.
