@IsonielNL @Magrath @riniah please try again

All working now thanks 😀

Hey folks, we recently added a "Certificate provisioning" health check to our status board:
  https://status.unraid.net/
It will automatically alert us when it detects a problem, this should allow us to resolve issues more quickly.

 

If you have provisioning issues in the future and the status board says everything is ok, please let us know! 

I Just tried, I see that the health tracker says that it is okay. I am getting no error, it just seems to time out.

I also seem to be having trouble with this, and the tracker says all good. I get an "Unraid root: Error: Server was unable to provision SSL certificate"

I'm getting the same error. Just updated from 6.9.3 to 6.11.5 Everything else seems to be working ok.

it just accepted the certificate for me, Im not what changed.

Sorry folks. We made further enhancements to the health tracker after yesterday's outage so it would be able to detect this issue. And more importantly, we are working on improvements to the infrastructure.

Reviving an older topic. Dealing with this issue today while trying to set up Unraid Connect remote access. Recieving the error that says "Error: Server was unable to provision SSL certificate", and I'm running Unraid 6.12.10. Any help is appreciated!
