Dear NCP users, I was using NCP on a raspberry 3 for a few months now and was quite happy. However, since two days I cannot login via the webinterface anymore, and my calendar apps (phone, pc,…) tell me they cannot sync because of a wrong/outdated security certificate. Thus I tried to run the letsencrypt command to get a new one. However, I always received the error, that the verification process of the certificate did fail and I should check my A/AAAA configuration. I do have port forwarding for 80 and 443 set up on my router. After some googling, I could renew the certificate by deactivating the “httpsonly” functionality in ncp. But still, I can’t access the webinterface of nc, nor can I sync my calendars - independent if I switch the “httpsonly” on or off. I can access the raspberry via ssh or the RASPBERRYIPADRESS:4443 from within the network though (how I could apply the above mentioned changes). The info panel gives the following output: ## System Info | NextCloudPi version | v1.10.9 | | --- | --- | | NextCloudPi image | NextCloudPi\_11-22-18 | | distribution | Raspbian GNU/Linux 9 \n \l | | automount | yes | | USB devices | sda | | datadir | /media/USBdrive/ncdata | | data in SD | no | | data filesystem | btrfs | | data disk usage | 931G/932G | | rootfs usage | 2.0G/15G | | swapfile | /var/swap | | dbdir | /var/lib/mysql | | Nextcloud check | ok | | Nextcloud version | 15.0.5.3 | | HTTPD service | up | | PHP service | up | | MariaDB service | up | | Redis service | up | | Postfix service | up | | internet check | ok | | port check 80 | open | | port check 443 | open | | IP | 192.168.178.2 | | gateway | 192.168.178.1 | | interface | eth0 | | certificates | [XXXXXXXXX.myfritz.net](http://XXXXXXXXX.myfritz.net) | | NAT loopback | no | | uptime | 11min | What else could I check/do?

Ok, so this looks like a repetition from this issue. I could solve it for now by deleting the `/etc/letsencrypt/live/WEB_ADDRESS` folder and then removing the -0001 from the folder `/etc/letsencrypt/live/WEB_ADDRESS-0001` Hopefully that works for you too! > [@Certificate is expired but not renewed](https://help.nextcloud.com/t/certificate-is-expired-but-not-renewed/50015): > > Hello, i have a problem with my NextcloudPi instance. My letsencrypt certificate is expired (as shown by my webbrowser) and is not automatically renewed. I tried to use ncp-config to get manually a new certificate but the output is Saving debug log to /var/log/letsencrypt/letsencrypt.log Plugins selected: Authenticator webroot, Installer None Cert not yet due for renewal Keeping the existing certificate - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Certifica… ---
