Traccar 5 doesn't work
What is not working exactly?
Okay so I double checked both versions and despite the /api/session not responding for both versions, 4.15 works and I can login normally, but with 5 it doesn't let me and throws 404 when trying to login.
On traccar 5 In the console i can see the following: 
Have you changed any code in the web app?
I did not, the only thing I'm changing is this in docker-compose:
traccar:
image: 'traccar/traccar:latest'
traccar:
image: 'traccar/traccar:4.15'
I also noticed that Traccar 5 can't connect to the db for some reason

I've seen similar issues. Maybe there's some problem with Java on Docker?
Could be, your response made me try debian image instead of alpine and it works just fine on traccar 5.
image: 'traccar/traccar:latest' = NOT work
image: 'traccar/traccar:4.15' = NOT work
image: 'traccar/traccar:5.0-debian' = work
So is "traccar:4.15" not working? Comments above indicate that it does. Are you sure it's the same issue?
traccar 5.0 crashes when I want to modify the properties of a user, thank you
You should create a ticket with details. But ideally you should try master first.
Hi,
After upgrading to traccar 5 in docker the web server seems to not start at all despite the docker running without any errors in the log.
If I change back to traccar:4.15 everything starts working. I know it's not a lot of information but I even tried to copy my current docker-compose and set up new folders for everything (essentially creating new db) but it still doesn't work.
Is there any way I can troubleshoot it further, like some debug flags? DB is created just fine, the connection between db and traccar is made but the webserver doesn't seem to work.
