Hello,

This morning I found my cluster was not synced anymore.
I've recently replaced my 1 year certificate with Let's Encrypt.
Therefore, I wanted to know if the renewal process has something to do with this error ?

Thanks!

Did you use PMG's Let's encrypt integration (available since PMG 6.4)?
If yes this error is unexpected (we added the updating of the fingerprints to the API calls which are used during certificate removal)

If not:
a) consider switching to PMG's integration
b) try running `pmgcm update-fingerprints`
(update-fingerprints is only available since PMG 6.4 - so you might need to update first)

I hope this helps!

Hello,

Yes, I've used the one from PMG 6.4 however it's still marked as "standalone" under ACME, is this expected ?
Here is for the first server (main) :

I'll see how it will go during the next renewal.

Thanks.

Yes - 'standalone' here means the 'standalone' plugin - i.e. the http-01 challenge (as opposed to the dns-01 challenge where you need to config access details for your domain's dns-service

did running `pmgcm update-fingerprints` resolve the issue?

Thank you for your answer.
I didn't know about `pmgcm update-fingerprints` and corrected the fingerprints in the cluster.conf on both servers. In case it's appearing again, I'll try.
