Sentinel 3 data WMS - nan values

Good evening,
I am trying to get Sentinel 3 SLSTR data from 2017 for a little bbox, I am interested in both S7 band and S2 band.
I get the data from WMS service using two different layers because S2 and S7 have different resolutions. For the 2017-01-02 20:51:35 image, I get data values for S7 band but ‘nan’ values for S2. Then I double-checked on EOBrowser if the data is actually missing: if I select the same datetime none of the S2 and S7 is shown on the map. I am wondering how I can get S2 data and why S7 is not displayed on EOBrowser.
This problem is not limited to that datetime but it occurs for one-third of the images of 2017.

Here below the parameter of my request:
MAXCC=100.0 Transparent=True ShowLogo=False BBOX=41.06116481189384%2C14.980955211017445%2C41.06219146883538%2C14.981723628557297 FORMAT=image%2Ftiff CRS=EPSG%3A4326 TIME=2017-01-02T20%3A51%3A35%2F2017-01-02T20%3A51%3A35 WIDTH=480 HEIGHT=847 LAYERS=PHENOLOGY-S3 REQUEST=GetMap VERSION=1.3.0

Thank you for the answer, here the detail you asked for:

  • link to eo browser Sentinel Hub EO Browser
  • the wms request for S7 band: https://creodias.sentinel-hub.com/ogc/wms/a890996e-64ec-4cad-*MASKED*?SERVICE=wms&WARNINGS=False&MAXCC=100.0&Transparent=True&ShowLogo=False&BBOX=41.06116481189384%2C14.980955211017445%2C41.06219146883538%2C14.981723628557297&FORMAT=image%2Ftiff&CRS=EPSG%3A4326&TIME=2017-01-02T20%3A51%3A35%2F2017-01-02T20%3A51%3A35&WIDTH=480&HEIGHT=847&LAYERS=PHENOLOGY-S3&REQUEST=GetMap&VERSION=1.3.0 and another similar wms request is done with different LAYERS parameter to get S2 band.

Thank you in advance


You will need to provide some more information so that we can check what is happening:
-links to the EO Browser location/date, which you say it is not working
-full WMS requests, mask just half of the instance ID.
