letsencrypt renew: Port 80 is already in use Topic is solved

[lanznaster]

I use the dietpi-letsencrypt command and changed the key size, but it didnt renewed since it was already done.

But now it is working, I've already tried the dietpi-letsencrypt before without changing the settings.

Well, it is good now, thanks for the support

Ok do you know what you did to get it working again. Curious to see what it fixed. Usually if you use DietPi tools for refreshing the cert, it should place a service that will go to refresh your cert automatically.

[lanznaster]

The only difference from my first try was changing the key value.
By the looks of it, next time that I need to renew it, this will happen. I'll make sure to document all my actions and update this post.

See you later and thanks again

usually a manual refresh should not be needed because certbot will place a service to check twice a day if a refresh is needed.

Code: Select all

[email protected]:~# systemctl status certbot.timer
● certbot.timer - Run certbot twice daily
   Loaded: loaded (/lib/systemd/system/certbot.timer; enabled; vendor preset: enabled)
   Active: active (waiting) since Sun 2020-04-19 23:58:21 CEST; 21min ago

I notice I do not have the trigger statement, is that ok?

[Joulinar]

looks like it's missing. can you have am check how the service looks like

Code: Select all

systemctl cat certbot.timer

as well you could do a restart of the service and check it again

Code: Select all

systemctl restart certbot.timer
systemctl status certbot.timer

Code: Select all

[email protected]:~# systemctl cat certbot.timer

After the restart, similar status with no trigger:

[Joulinar]

what I still found strange is that certbot is adding a randim timer. Not sure where this is coming from

Code: Select all

certbot.timer: Adding 28min 1.794925s random time.

pls can you check all systemctl timers

Code: Select all

systemctl list-timers --all

[lanznaster]

hmm the certbot timer is there ans seems active. As well it seems running every 12h, which is correct. Maybe we need to wait until your cert will be expire to see if it will be refreshed automatically
