Did you try curl http://<server-address>:8080 and curl http://<server-address>:8008 from the development machine?

How exactly did you configure your clearml.xonf file? Can you share the api section?

api {

web_server:  http://10.3.19.183:8080 
api_server:  http://10.3.19.183:8008 
files_server:  http://10.3.19.183:8081 
verify_certificate = False
credentials {
    "access_key" = "M3Q7QA2TT48OHV6MMFVW"
    "secret_key" = "r7s6axxIpKsNT9sQrxSfsTdZOZti2TS9eJVN9mTVYUqRa15HZT"
}

}

Can you curl http://10.3.19.183:8008 from your workstation?

Yes, I tried it. Getting Json response from both urls. 8080 portal is accessible and I could generate credentials as well which I pasted for clearml-init but doesn't work there
