    Hi,
    I am just trying to start with mETL but after starting mETL on a windows system I am not able to connec to the mETL service.
    I have started it in a cmd window and installed it as a service and it seems running fine.
    But connecting to http://0.0.0.0:42000/metl or localhost:42000/metl gives the same error; localhost has refused the connecton.
    Anyting else to check? (NB: firewalls are turned off!!!)

      Already solved: just too little memory to start up!

    Hi ruben,
    I'm trying to start with mETL but after starting mETL on a windows system I am not able to connect to the mETL service. I followed Standalone procedure to install, went good. After that, I installed Metl as service and when i'm trying to start the service, it showing error 'StartService returned error 1053: The service did not respond to the start or control request in a timely fashion'.
    and also when i'm trying to connect to http://0.0.0.0:42000/metl or localhost:42000/metl gives the same error; error 503: service unavailable. anybody can help how to fix this issue.

    Thanks.

    I would try a couple things.
    1. Check the log files (under the logs folder where you selected to install Metl) wrapper.log, install.log and metl.log See if you find any additional errors from install or initial startup then post the error if you can't figure out how to address.
    2. Make sure you are an administrator on the Windows machine you are installing on or run the install as administrator.
    3. Install from a clean slate choosing the smallest memory option (Small - 256 MB). This can always be adjusted later after install depending on the available system resources.
    4. Make sure you have Java 8 installed (not newer versions at this point).

    Thanks Nathan for your response. In the log files, i have only install. log and Install_V3.4.3_20190702140015_5416095038839426512 stating that 'StartService returned error 1058: StartService returned error 1053: The service did not respond to the start or control request in a timely fashion.
    Native error 19'
    i Dont know how to resolve this issue. I tried by adding services pipe timedout with value 180000 Decimal but problem is not solved.! and i followed the rest 2nd,3rd and 4th points.
    I'm using windows server 2016. I dont know that this is the problem.!

    I think it might be having an issue finding the correct Java version.
    In the metl/conf/ folder open the metl_service.conf file and explicitly enter the path to the java executable like below (I have found at times you need to make sure there are no spaces in the path to it):

    wrapper.java.command=C:\ProgramData\Oracle\Java\javapath\java.exe

    The other thing to check is in regedit look for
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\metl
    ImagePath - make sure the java executable at the start of the value is pointing to the correct version / instance of java on your machine.

    While replicating on my pc I just found that my services had created with the java path double quoted and I got the same Native error 19. I went into regedit and updated the ImagePath by removing the double quotes around the java path and it started to work. I do believe there still is the requirement or need to have no spaces in your path.
