Description of my issue

since yunohost version i´m unable to renew Let s encrypt certificate.

I receive a mail every day like this:

Url: http://muc.mydomain.ynh.fr/.well-known/acme-challenge/QbfEA98PPj6aPZ2UH-l44-ytGjBX-yqPjd9WEXoFENQ
Data: None
Response Code: None
Response: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1123)>

here the full logs:

Thank you for your help.

Does the diagnosis complain about something like manually changed configuration ?

no only applications flagged as broken Kanboard, Netdata,Guacamole

yunohost tools regen-conf says

/etc/ldap/slapd.ldif’ has been manually modified and will not be updated

Considering that you’re on 11.1.3, and assuming that you ain’t using XMPP, I would go to Domains > yourdomain.tld, and disable ‘XMPP’ in the features

Thank you ! That solves my problem.

Service metronome is stopped now in diagnosis after this warning:

Same problem here since 11.1.2, not resolved with 11.1.3.

No problem on diagnosis page.

Working after disabling xmpp, but it’s only a temporary fix (I need XMPP but certificate was very close to expire so I may not use it while the bug is fixed)

Same problem here too on a VPS running Debian 11.6. It started with 11.1.2, and is not resolved with 11.1.3.
My domain had expired, trying to renew it ran into the same certificate verify failed: unable to get local issuer certificate error.
Disabling XMPP did the trick (sudo yunohost domain config set mydomain.tld feature.xmpp.xmpp -v no)
Then renewing the certificate worked (sudo yunohost domain cert renew mydomain.tld), although it showed the following warning, which I assume to be related to having just disabled XMPP:

Job for metronome.service failed because the control process exited with error code.
See “systemctl status metronome.service” and “journalctl -xe” for details.
Warning: Could not execute the command ‘systemctl restart metronome’

Diagnosis shows the following warning & errors (nothing new, apart from the metronome/XMPP ones): https://paste.yunohost.org/raw/adudecajag
