I keep getting expiry warnings:
Your certificate (or certificates) for the names listed below will expire in 9 days (on 01 Jun 20 12:29 +0000).
apps.menne-biomed.de menne-biomed.de www.menne-biomed.de
Testing these with SSL Server Test shows that expiry is on July 8. The same on the server:
~>./checkssl apps.menne-biomed.de apps.menne-biomed.de 443 apps.menne-biomed.de (alt) Jul 8 18:19:29 2020 GMT Let's Encrypt Authority X3 ~>./checkssl menne-biomed.de menne-biomed.de 443 menne-biomed.de (alt) Jul 8 18:19:29 2020 GMT Let's Encrypt Authority X3 ~>./checkssl www.menne-biomed.de www.menne-biomed.de 443 www.menne-biomed.de (alt) Jul 8 18:19:29 2020 GMT Let's Encrypt Authority X3
I assume there is some hidden SSL that is active in addition, but I cannot find the date 01 June anywhere in expiry.
My main domain (menne-biomed.de) runs on nginx directly, but some others (apps) run in Docker containers. So I suspect that there is some competition, but why does SSL test only see the July-expiry ones?
