Mailcow is to stop working on its own!

Hello everybody,

My mailcow server completely stopped working this morning.
However, this one has been working fine for 1 year.

I started getting certificate errors so I tried updating the certificate with the acme container

The interface no longer works and the curl (ip) tells me: Failed connect to hide:80; Connection refused

If anyone would help me… thanks in advance

Does another service now use port 80? Is something else running on that Docker host claiming the port 80?

[root@mail ~]# netstat -tulpn | grep LISTEN | grep :80
tcp 0 0 127.0.0.1:80 0.0.0.0:* LISTEN 5108/docker-proxy

All have been working fine for 1 year. I haven’t touched anything since!

You haven’t touched anything? Like installing additional containers? Why is port 80 then only listening on the local interface 127.0.0.1?
Seems not mailcow is broken, but something in your docker configuration.

Mailboxes no longer work.
Thunderbird gives me a connection error on all mailboxes.. (SSL type).
I haven’t been touched since April 2022..

The VPS is only used by mailcow..
I’ve tried a lot of things, even updating, nothing works.

Thanks,

Sure, Lets Encrypt certificates are only valid for 3 months, and with your configuration it cannot update.
Please use the link I posted above how to investigate logs.
Try to find out why docker is not binding the ports correctly to the docker host IP address.

I don’t know docker..
I’m going to try to recover my data and stop with mailcow, because my whole company has been without a mailbox for 2 days..
I have over 100,000 emails on the server..

Thank you anyway for your help.

Welp, maybe that’s the best decision. I don’t know why your company relies their whole email on a technology they don’t know how to use. Maybe the problem is that you haven’t touched Mailcow since April 2022. There were some critical updates in the meantime.

So you are saying you change the product because you are not able to read the logs and dont understand docker?
And you are running a company on top of that? Unbelievable…

Do you have to be a computer technician to run a business?
Your life must not be very interesting to make this type of answer.
Sad world.

@D4niel
It was not me who manages this, the person is no longer with our company…

If the Staff can mark this thread as resolved..!
Thanks!

jimmyr57000 No you have not to be a computer technician. But if you are running services for a business, you should have at least two technicians who are able to operate the IT services you need (if you lose the only one who knows it). There is always the option to have that service managed, like Servercow or Office365, no risk on your side then.
Sad, that you were not aware of this IT best practice.
