I am again experiencing the error I reported here:




Repeatable (retry always fails) HTTP 500 errors for certain dates Bugs & Features


I am running large numbers of WCS requests through the EO-learn library. I request LAI time series data for areas of 0.1-10 hectare land parcels for ca. 6 month time intervals.
Occasionally (ca. 1% of the time), the EO learn workflow.execute() call will fail because of a HTTP error:
“DownloadFailedException: During execution of task S2L2AWCSInput: Failed to download from:
https://services.sentinel-hub.com/ogc/wcs/?SERVICE=wcs&BBOX=660977.0343447%2C5689713.093569177%2C661295.2431077849%2C56900…


The only difference, I get the error code 400 not 500. The code I use is the same as in the above linked topic.

The following request (generated by the sentinel-hub library) fails:

with HTTPError:

As in the linked topic, changing the maxcc parameter to 100 solves the problem.


I’d appreciate if you could investigate.


Cheers

As last time, changing the maxcc to 100 sometimes solves the problem, but other times not.

The following fails:

Can you let us know first two parts of the instance_id, so that we can identify the configuration you are trying to run?

First 2 parts of instance ID i’m using: b479e2f7-530d
