Camunda Web Modeler is not able to deploy

We are getting the issue again in web modeler while deploying the process its giving error Deadline Exceeded.
We have TLS enabled, so provided web-modeler-restapi with ZEEBE_CA_CERTIFICATE_PATH and provided the issuer CA certificate, but seems like its not picking up.
We can see the certificate available in container. And we have also increased the timeout values in environment variables as per troubleshoot guide.

We also tried to provided the cacert truststore with the CA certificate imported with Java Tools Environment variable to override the current truststore, but that is also not working.

Can you please suggest if there is any extra configuration required if we have TLS with certificated issued by CA.
Our current web modeler version is 8.5.3.
