Certificate.crt is missing

Hello everybody, I am trying to setup a default matrix server with playbook.While installing I am getting the following error:

matrix-chat matrix-traefik-certs-dumper-matrix.matrix.mydomain.com[20334]: /matrix/traefik-certs-dumper/dumped-certificates/matrix.matrix.mydomain.com/certificate.crt is missing

Anybody any idea what could be wrong? Thanks for some help

Well, the file is missing. How did you install it?

I know, but I thought the playbook is doing everything. I did follow this one:

https://computingforgeeks.com/how-to-deploy-matrix-server-using-ansible-and-docker/

I kept the original vars.yml given on examples

I’ made a terrible mistake and installed everything on one server…stupid me…now it is working sorry for wasting time for you guys…
