Problems with traefik assigned certificate

In have a docker/node site hosted on DO.

Everything working fine before adding a security certificate

I have set up the remote target to install a certificate on the domain (as i have done several times in the past) with the below settings

Everything installs correctly to the DO droplet

I am getting this error showing the certificate is installed but is invalid

Anyone any ideas?

Re deployed container and it has started working.

Also in case of problems, you can check the server logs:

Further more very useful links to see the Let’s Encrypt certificate renewals and logs:

https://crt.sh/ - the most useful for listing all the renewals history of all the cert names
