Hi, I am setting up a thredds data server on a local machine to serve some data for private use within our research group. I have used the docker image *unidata/thredds-docker:latest* to install and setup the server. I have also managed to create and add a catalog. After setting up the server, I have noticed a peculiar behaviour. If I use tools like *nco* etc. on the machine where I have installed a thredds server, I am able to access the data. However, when I try to access the data from a different machine, I get a syntax error. I have tested to see if the file is accessible from the thredds server. Below, you can see the output from *ncdump*. ncdump -t -v time http://138.194.55.191/thredds/dodsC/worldclim/historical/2.5m/prec/wc2.1_2.5m_prec.ncnetcdf wc2.1_2.5m_prec { dimensions: time = UNLIMITED ; // (12 currently) lat = 4320 ; lon = 8640 ; variables: double time(time) ; time:standard_name = "time" ; time:long_name = "time" ; time:units = "months since 1985-01-01" ; time:calendar = "standard" ; time:axis = "T" ; time:_ChunkSizes = 512 ; // "2027-09-01" double lon(lon) ; lon:standard_name = "longitude" ; lon:long_name = "longitude" ; lon:units = "degrees_east" ; lon:axis = "X" ; double lat(lat) ; lat:standard_name = "latitude" ; lat:long_name = "latitude" ; lat:units = "degrees_north" ; lat:axis = "Y" ; float prec(time, lat, lon) ; prec:units = "mm" ; prec:_FillValue = -32768.f ; prec:missing_value = -32768.f ; prec:long_name = "precipitation" ; prec:_ChunkSizes = 1, 7, 8640 ; // global attributes: :CDI = "Climate Data Interface version 1.9.3 (http://mpimet.mpg.de/cdi)" ; :history = "Thu Apr 30 17:43:57 2020: GDAL CreateCopy( ./ wc2.1_2.5m_prec_01.nc, ... )" ; :GDAL_AREA_OR_POINT = "Area" ; :GDAL = "GDAL 2.1.3, released 2017/20/01" ; :CDO = "Climate Data Operators version 1.9.3 (http://mpimet.mpg.de/cdo)" ; :Conventions = "CF-1.5" ; :DODS_EXTRA.Unlimited_Dimension = "time" ; data: time = "1985-01-01", "1985-02-01", "1985-03-01", "1985-04-01", "1985-05-01", "1985-06-01", "1985-07-01", "1985-08-01", "1985-09-01", "1985-10-01", "1985-11-01", "1985-12-01" ; } When I try to access the file using* ncks* e.g., ncks -d time,0,1,1 -v prec http://138.194.55.191/thredds/dodsC/worldclim/historical/2.5m/prec/wc2.1_2.5m_prec.nc temp.nc I get the following error syntax error, unexpected WORD_WORD, expecting SCAN_ATTR or SCAN_DATASET or SCAN_ERROR context: <!doctype^ html><html lang="en"><head><title>HTTP Status 400 – Bad Request</title><style type="text/css">body {font-family:Tahoma,Arial,sans-serif;} h1, h2, h3, b {color:white;background-color:#525D76;} h1 {font-size:22px;} h2 {font-size:16px;} h3 {font-size:14px;} p {font-size:12px;} a {color:black;} .line {height:1px;background-color:#525D76;border:none;}</style></head><body><h1>HTTP Status 400 – Bad Request</h1><hr class="line" /><p><b>Type</b> Exception Report</p><p><b>Message</b> Invalid character found in the request target.
