    Thank you for this! That helps me a lot because I had nginx 502 Bad Gateway each hour at 58 minutes.

    But I updated the SSL It! Extension since v1.8.5-1210 seems to resolv this issue: 

    1.8.5 (12 June 2021)

    • [-] The extension no longer reassigns an already issued Let's Encrypt certificate to a domain every hour if its mail component should not be secured. (EXTSSLIT-1645)

    Despite the update, I still have the problem. I use the LiteSpeed ​​extension as a web server instead of Apache. Does that have an impact? Are there other approaches? Thanks for the help! All websites are offline for about 1 minute every hour ...
