Server Started, unable to connect


Hi Guys,

I am hoping someone can help me with figuring what is broken or what i messed up in setting up the MatterMost server.

I’ve tried to setup the server following the install guide here.

with MySQL and running on Centos 7.

by the looks of things the service does start however not fully as i am unable to browes to it remotely and curl locally give and error.
The error is similar to the case here. [SOLVED] Server started but app not connecting and no logs
Unfortunetly my knowldge is now where near deap enough so i was not able to enable the loging or the DB loging.

Hi @Iconically_Lost,

As a first step, please take a look at this troubleshooting doc for tips:



Thank you for the link, I’ve had a read through and it looks like most of this covers topics where you are at least able to get some connection to the site. From the client side we get zero connectivity. I’ve tried going through the logs, but unfortunately nothing jump out.

As per my linked thread, how do i enable the general loging and DB loging?


Hi @Iconically_Lost,

You can set your file log level (in System Console > General > Logging) to DEBUG , which will print high detail logging to debug issues.
