[SOLVED] ACME-DNS certificate renewal failed PM VE 7.4-3

you can remove the custom certificate and key (/etc/pve/pveproxy-ssl.*) and restart pveproxy (systemctl restart pveproxy) to revert to the self-signed certificate. then you can retry obtaining one from Let's Encrypt.. if that shows the same symptoms again, please post the full journal output covering that time period, as well as any other task logs and messages
 
yes! now i can log in! i will apply for a new certificate, hopefully everything will go smoothly
the path you gave me was missing a /local/ :D

rm /etc/pve/local/pveproxy-ssl.*
