I have worked like 2 years with Zimbra and there was no problem, like 6 months ago, I installed Let's Encrypt SSL Certificate to get zimbra HTTPS web client, I have followed the tutorial: ... ertificate , and it went fine, but now, some users are telling me that their web clients quit suddenly to the login page, I thought it was the certificate has expired, but it is normal, and when I am writing an email, the state changes from https (secure) to unsecure, is this normal? it happens only when I am writing an email. Hope anyone has an answer.

Hi Marcelo
I've discovered that some users does get stuck when the certificate renews

I've also followed that guide - and do not having thios issue.
I've created the following for handling the renewing of certificate

Code: Select all

01 22 */15 * * /scripts/

# This script nrenewing the letsencrypt certs

# Starting the script
/bin/systemctl stop apache2

sleep 3

/usr/bin/certbot renew --pre-hook "/usr/local/bin/ -p -j" --renew-hook "/usr/local/bin/ -r -j"

I found a guide for forcing all trafic through zimbra to https from http
