Hello,
today after installing mailcow I have a problem with PHP.
It doesn’t start and there is a problem with launching the website.

mail_php-fpm-mailcow_1 standard_init_linux.go:228: exec user process caused: exec format error, user process caused: exec format error, standard_init_linux.go:228: exec user process caused: exec format error

`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, remove all volumes and start over (NEVER do this with a production system, it will remove ALL data):

docker-compose down -v ; 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.
