< p > This error tries to tell you that one of the (health) conditions for a certain container are not met. Therefore it can't be started. This can have several reasons, the most common one is an updated git clone but old docker image or vice versa.< / p >
< p > A wrong configured firewall could also cause such a failure. The containers need to be able to talk to each other over the network 172.22.1.1/24.< / p >
< p > It might also be wrongly linked file (i.e. SSL certificate) that prevents a crucial container (nginx) from starting, so always check your logs to get an idea where your problem is coming from.< / p >

< p > Please check your local firewall!
Docker and iptables-based firewalls sometimes create conflicting rules, so disable the firewall on your host to determine whether your connection issues are caused by such conflicts. If they are, you need to manually create appropriate rules in your host firewall to permit the necessary connections.< / p >
< p > If you experience connection problems from home, please check your ISP router's firewall too, some of them block mail traffic on the < em > SMTP< / em > (587) or < em > SMTPS< / em > (465) ports. It could also be, that your ISP is blocking the ports for < em > SUBMISSION< / em > (25).< / p >
