My colleague installed a wildcard SSL cert for his domain neveah.art, and another at angelluc.nl .
The sites are working but the SSL test at ssl labs lists an extra certificate for neveah.art which is registered for the domain *.angelluc.nl .
See certificate 2 on the list:
However, when i run
certbot certificates there is only one entry for *.angelluc.nl
I cannot see any reason why nginx would be serving the second one.
