Solved license_error.HttpsErr_InvalidResponseHeader

[Gnomx]

Hi there.
I've a problem with 3CX.
This works fine up to 3 days ago. So when I try to open browser in order to manage software i get registration page and when i try to insert license key i get this error : "
license_error.HttpsErr_InvalidResponseHeader ".

So i've tried to change DNS and restar servicies , but anything changed...
So any solution? Thanks.

HttpsErr_InvalidResponseHeader sounds like that you have an firewall with HTTPs inspection, as the PBX does not understand the expected answer from 3CX anymore... What firewall do you use?

 

[Gnomx]

We don't use any kind of firewall.

So anybody can Help me....
I'm not using any kind of firewall or virus software.
Cheers

Your ISP may be using a firewall, have you run the firewall checker and if so did it pass?

the reasons are that you are on a non-activatable version, you must be on V15.5 SP6 at least, currently, you have a V15.0

You will not lose any data / config using the tools.

With all updates, make sure you have a valid backup of the 3cx system before doing the ipdate

Did you setup schedule backups of the 3cx system, if so backups should be in the location you specified.

Not sure if your version has backup command line, you could check and run a backup if it does https://www.3cx.com/docs/backup-restore-command-line/

Hi Gnomx,

The default location would be here: C:\ProgramData\3CX\Instance1\Data\Backups

Check to see if you made any backups and use the latest one

Yes I have a backup inside this folder.
But i can't update it by using upgrading tool. It doesnt work

Hi Gnomx,

What happened when you ran the upgrade tool? Can you post a screenshot to show why it didn't work?

The correct way to do it is:

1. Download the tool on the PBX server
2. Right click and run it as administrator 3CX WinUpdater.exe
3. Take a screenshot of the output

Important: Remember to take a copy of your backup file first and store in on another machine or drive
