Donna, The LDM configuration-file on Earthdata contained the following: # Giving permission to your own machine and Unidata # # Under no circumstances comment out the next allow entry to localhost # The LDM will NOT start if the lines are commented out. #allow ANY ^((localhost|loopback)|(127\.0\.0\.1\.?$)|([a-z].*\.unidata\.ucar\.edu\.?$)) Note that the line that must not be commented-out is, instead, commented-out. I recommend replacing the above with the following: ALLOW ANY ^(localhost|loopback|127\.0\.0\.1)$ ALLOW ANY ^[a-z].*\.unidata\.ucar\.edu$ If you want, you can omit the Unidata entry because we can't reach Earthdata anyway. Please let us know if this fixes the problem.
