Hello,

I have a problem regarding mailcow installation.
I get the following information in the browser:

What is happening?

Please do not stop the stack while we are initializing the database or do other preparations.

What is happening? - Nginx cannot connect to an upstream server or other services are not ready yet.
This is fine if mailcow was just installed or updated and can take a few minutes to complete.
Please check the logs or contact support if the error persists.

Quick debugging

Check Nginx and PHP logs:

docker-compose logs –tail=200 php-fpm-mailcow nginx-mailcow
Make sure your SQL credentials in mailcow.conf (a link to .env) do fit your initialized SQL volume. If you see an access denied, you might have the wrong mailcow.conf:

source mailcow.conf ; docker-compose exec mysql-mailcow mysql -u${DBUSER} -p${DBPASS} ${DBNAME}
In case of a previous failed installation, create a backup of your existing data, followed by removing all volumes and starting over (NEVER do this with a production system, it will remove ALL data):

BACKUP_LOCATION=/tmp/ ./helper-scripts/backup_and_restore.sh backup all
docker-compose down –volumes ; docker-compose up -d
Make sure your timezone is correct. Use “America/New_York” for example, do not use spaces. Check here for a list.

After running docker-compose logs … I get this:

I am running a normal website on my server where I tried to install mailcow. My DNS configuration (Cloudflare) looks like this:
TXT - domain.de - “v=spf1 mx a -all” - DNS only
TXT - _dmarc - “v=DMARC1; p=reject; rua=mailto:admin@domain.de” - DNS only
MX - domain.de - mail.domain.de - Prio 10 - DNS only
CNAME - autoconfig - mail.domain.de - DNS only
CNAME - autodiscover - mail.domain.de - DNS only
A - mail - IPv4 address - DNS only
A - domain.de - IPv4 address - Proxied (which redirects to /var/www/domain on the server directory.
