Hello! For reasons I don't understand, let's stop working on Let's Encrypt. That is, on sites where it was previously included, it continues to work, but it does not turn on for new ones. I go into the properties of the site, tick Let's Encrypt save, and after a while it disappears. I tried to reinstall it, but nothing happened. Ubuntu system installed 18.04 Please help.
Normal situation is caused by your LE client being outdated and updating it normally fix it. However, for certainty, do check your LE log for error or use LE faq to find fault.
I did as instructed, did not help. All versions are recent. For all sites it works, for one it does not want.
