This could be my experience, below my experience, looks the same.
No one with experience on this subject?
My story:
I’ve searched and searched, but haven´t found it.
I have a running Mailcow docker install and installed using the helper script Nextcloud.
I installed and downloaded nextcloud mail and am trying to connect it.
All descriptions say to use the external url (mailcow.domain.ext), but it doesn´t work using ssl or cleartext. Also using the internal IP does not work.
Since it hasn´t been documented and I must be doing something wrong, here’s the question:
Has anyone succeeded in getting this to work?
Steps to reproduce:
Install and configure mailcow, using mailcow documentation
install Nextcloud using the third party script
Install Nextcloud mail and try to connect using the user interface
Ubuntu 22.04 lTS
dual cpu 8Gb mem
Docker: 24.0.6, build ed223bc
compose: v2.9.0
Mailcow version: 2023-10a
PS: Nextcloud can communicate with Collabora container, separate docker container (took some time too, it is functional as far as I can see)
Thanks!
PS: the backup script is missing the Nextcloud file data, as also the complete website content, I fixed this in my backup script. If someoneś interested, let me know.
