All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/www.bureaubureau.dk/fullchain.pem (failure)
/etc/letsencrypt/live/bureaubureau.dk/fullchain.pem (failure)
2 renew failure(s), 0 parse failure(s)

Can anyone tell me how to fix this issue. I have gone through similar questions but nothing helped. So please have a look!
