Hi @iLab
checking your domain there is a wildcard certificate - https://check-your-website.server-daten.de/?q=communityilab.ca#ct-logs
| Issuer | not before | not after | Domain names | LE-Duplicate | next LE |

So you have to use dns validation.
Creating these certificates you may have created a TXT entry manual.
So do that again. renew doesn't work with a manual action.
