My domain is: app.cosmo-jpn.jp
My hosting provider, if applicable, is: Microsoft Azure
I can login to a root shell on my machine (yes or no, or I don't know):
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): Azure Portal
We actually have 3 deployment slots, which has 3 different domain names like below:
- Production - app.cosmo-jpn.jp
- Stage - app-stage.cosmo-jpn.jp
- Stable - app-stable.cosmo-jpn.jp
We have Azure Let's Encrypt extension and a web job running which should renew the certificates after 1.5 months.
We noticed that the renewal hasn't been run as it should have been, so we ran it manually for production and stage manually yesterday, and it was a success. We left stable as is to see if we can find out the problem.
We'd really appreciate if you someone could point out the way to troubleshoot and find out the cause why this hasn't worked.
