Tag Manager Plugin keeps deactivating itself

Hi, I have a problem with matomo on Premise.
Since weeks I want to setup Tag Manager, and I know I need to activate the plugin. So I went to the settings sections, plugin, and Enabled Tag Manager.
After one hour, it was deactivated for no reason.
So I enabled it again, and next day I checked, and again it was disabled.
Has someone had this problem before? What can I do?

Thanks for you help!

Hi @l.gamero
Do your Matomo run on several servers (via load balancer for example)?
If so, then the configuration file must be shared between each server, because this plugin activation is written by Matomo in the configuration file. (during your test, you reach first a server, then later another one, I thinkā€¦)
