TLS certificate renewal failing with Let's Encrypt

Thanks for the suggestion. Unfortunatly it didn’t worked for me. I’m already moving out. I’m kinda done since 0.19b MIAB keeps bugging like hell for me. Every time you post something in here I got the impression that it ends up “You must have fucked up your settings” which isn’t the case. I’m not a super techie wizzkid but one thing I learned from a guy who is, don’t fix it when it’s not broken and because I’m hosting several domains for friends and family I don’t dare to touch the MIAB for fucktarding around. The box is beside normal security updates unattended. If every troubleshoot here ends up that way and MIAB is costing me more time than it delivers me (one of the main reason why to bundle all those domains together on one platform) than I guess I’m going to try my luck on another mail platform.
