SSL renewal error


I have following problem with NextCloudPi:

Nextcloud version:
NextCloudPi version: v1.35.0

The issue you are facing:
My NCP config runs quite well since mid of last year. I only have the issue that the automatic renewal function for the letsencrypt SSL certificate does not work. A manual update is possible, if I just start the letsencrypt tool in NCP again. So this is ok as a temporary workaround. If I remeber correctly, the problem occured after I reinstalled NCP and restored a backup.

Error message in the web interface is:

SSL renewal error
SSL certificate renewal failed. See /var/log/letsencrypt/letsencrypt.log

letsencrypt.log shows following information

Via SSL Labs I tested my certificate. Following output:

|Valid from |Mon, 01 Mar 2021 12:26:50 UTC|
|Valid until |Sun, 30 May 2021 12:26:50 UTC (expires in 1 month and 17 days)|

So from timing perspective the certificate should have renewed.

Any ideas?

Best regards

So not due for renewal yet, not for another 18 days.
Certs are valid for 90 days and auto renew after 61 days, afaik.

Ok, so maybe I need to wait.
But this does not explain the error message. And according to the web interface the cert will be renewed every month.

Same issue here !

You were right. The cert has been updated in the meantime.

Nevertheless I still get the error message. Strange thing is that only one user account receives these messages. I have 2 accounts and both are admin.

Further ideas?
