Hi to all, I’m here today because I’m (dumb) stuck with my token management, I did some mistakes managing this.I installed multiple Centreon instances in my test momentum (tried differents linux distros because of some bugs with exports or graphs), before to take care of the mention that i’m able to activate the token on only 3 instances, and obviously I destroyed the 2 others testing VMs without dissociate the token...Btw, I still have the last testing VM, I can use the button to dissociate the token from my last testing instance, that visibly sounds good but after that i’m not able to associate the token on the brand new VM.Centreon accepts the token but tells me “already activated with 3 other instances”, and asks me to choose a subscription.I can certifiate that I only have 1 instance being and running and dissociated, I tried the tips mentionned in others threads :-checked the API url, that’s ok and responds-checked the license manager log ("message", "No subscription found.")-tri

Hello,I’m encountering an issue with the Centreon API (v24.10) when retrieving downtimes.Sometimes, without explanation, API returns an empty response even though a downtime is correctly created and active at the moment of the request. {    "result": [],    "meta": {        "page": 1,        "limit": 10,        "total": 0    }}Could you let me know why the API returns this empty result while a downtime is currently active?Is there any known behavior, specific condition, or configuration that could cause this intermittent response? Note that this is the same response we receive when there is no downtime in progress.Therefore, this does not allow us to detect the error. Thank you for your help.

Hello,Since the update to Centreon 24.10.10, all my monitoring connectors appear greyed out in the Web UI. I can no longer update them or install new ones.I am now running 24.10.14, but the issue is still present.Here are the checks I have already performed: The fingerprint shown in the Web UI matches exactly the one stored on my server. The license type is correctly detected. I am well below the limit of 100 hosts (IT100 license). No hardware changes have been made. The issue appeared immediately after the 24.10.10 update and did not exist before. The 24.10.14 update did not fix the problem. Could you please tell me if this issue is known, or if there is a procedure to reactivate the monitoring connectors correctly?Thank you in advance for your help.Best regards,Florian
