SSL errors DuckDNS after snapshot restore

After having a lot of issues for 2 days with 0.113, I restored a full snapshot from May to a Raspberry Pi. My SSL connection setup with DuckDNS is not working. I get SSL errors on the certificate that it is not trusted.

Anyone point me in the right direction what I need to do ? Thanks

Looks like you hit a rate limit.

From the link:

If you’ve hit a rate limit, we don’t have a way to temporarily reset it. You’ll need to wait until the rate limit expires after a week.

I ran into something similar after rolling back to a previous snapshot. The only difference is I only rolled back 1 day but it happened that my let’s encrypt cert updated a day after the snapshot was taken. I ended up going back to the current snapshot which had the latest cert.

If you change your domain name that should start a new certificate request.
