Add sequential flag.
First, NEVER send a PR to master branch, it will NEVER be accepted. Please send to the dev branch instead.
If this is a PR to support new DNS API or new notification API, please read this guide first: https://github.com/acmesh-official/acme.sh/wiki/DNS-API-Dev-Guide
Please check the guide items one by one.
Then add your usage here: https://github.com/acmesh-official/acme.sh/wiki/dnsapi
Or some other wiki pages: https://github.com/acmesh-official/acme.sh/wiki/deployhooks https://github.com/acmesh-official/acme.sh/wiki/notify
I think LetsEncrypt / Ubuntu is failing because GitHub Actions secrets aren't passed to PR builds.
@Neilpang Is there any interest in this?
sorry.
Ping @Neilpang
+1 for this. Without sequential verification it's impossible to generate wildcard certificates using DNS-01 challenge with DuckDNS (getssl works instead, but I'd really prefer to use acme!).
