Backend not forwarding properly after upgrade to 1.14.x/1.15.x

[lord-kyron]

Hi,
I started using seatsurfing recently and I deployed version 1.13.8 in Kuberentes with the guide provided in the official documentation.
I've set it up as described Traefik ingressRoute + Nginx reverse proxy before it and it was running great.
However, I decided to upgrade to 1.15.0 latest version - suddenly the backend stopped working giving me this error:
Get "http://localhost:3000/admin/dashboard": dial tcp [::1]:3000: connect: connection refused
and respectively this for the UI:
Get "http://localhost:3001/ui/login": dial tcp [::1]:3001: connect: connection refused
I tried to deploy a new separate setup with 1.15.0 to start from scratch - it was giving me the same error from the start.
I also tried a new setup from scratch with 1.14.4 - the effect was the same.
So for now only 1.13.8 works for me and I can't understand why.
I am using the documentation as example how to deploy all the version - maybe something changed in 1.14/1.15 which is not properly added to documentation?

I don't know.
Can someone suggest how can I fix this and run a more recent version?
Thanks!
P.S. - here is my setup (URL are changed on purpose):

Someone to help with this one?

Hi @lord-kyron,
the Kubernetes documentation is missing instructions on how to use Seatsurfing with separate Admin UI and Booking UI containers. Please refer to the Docker documentation for now:
https://seatsurfing.app/docs/getting-started/
You'll need to set the BOOKING_UI_BACKEND and ADMIN_UI_BACKEND environment variables.

Same problem. The documentation of the environment variables doesn't help me much. 1.13.8 works, any higher version gives a connection refused to localhost:3000 oder localhost:3001.
Runnnig on kubernetes cluster at digitalocean.
Any additional help?

i guess we face the same issue #195
i am currently running backend:1.17.0 and booking-ui/admin-ui on 1.13.8 which is the only combination which works for me right now.

i think this is fixed with 1.19.5.. i could without any issues update my booking-ui and admin-ui to this version.
