Timescale DB does not start(docker) after restore(outside of Kubernetes cluster) from s3 bucket

i’m using timescaledb single HA helm chart to deploy on self hosted Kubernetes 3 node cluster:

I have configured backups to s3 bucket.
all is working
restore inside the cluster is working

I was trying to restore outside of the cluster using PGBackRest with the correct configurations from the same S3 bucket (poddb stanza)

for outside cluster I use the following docker image to deploy my Timescale DB via docker compose:
timescale/timescaledb:2.9.1-pg14

before restore I have turned down the timescale db server and cleared the db data directory

the pgbackrest restore is working, and I can see the backup files are now inside the db data directory

once I restart the timescale db service i get the following error:
FATAL: could not load server certificate file “/etc/certificate/tls.crt”: SSL error code 2147483650

this is the full log:
C:\nms_git\enc\modules\gnss\docker>docker compose -f docker-compose-db.yml up

Can you please help to find out the problem?

thanks,
