New HTTP 500 error

I have been successfully doing batch WCS requests using the EO-learn library for several weeks (besides the problems solved a few days ago - Repeatable (retry always fails) HTTP 500 errors for certain dates).
Today, after successfully running some requests, I suddenly am getting a new HTTP 500 error for all new requests. I have changed nothing in the configurator or in the requests in this time (it happened mid-way through a loop making requests for lots of different small areas).

Example request:
https://services.sentinel-hub.com/ogc/wfs/#####?SERVICE=wfs&REQUEST=GetFeature&TYPENAMES=DSS2&BBOX=649967.0158626655%2C5679849.603646094%2C650143.460839879%2C5679985.275708557&OUTPUTFORMAT=application%2Fjson&SRSNAME=EPSG%3A32631&TIME=2019-05-01T00%3A00%3A00%2F2019-08-17T23%3A59%3A59&MAXCC=90.0&MAXFEATURES=100&FEATURE_OFFSET=0

error:

com.sinergise.sentinel.configuration.WmsLayer["datasourceDefaults"]->com.sinergise.sentinel.s2.S2L1CDatasourceAttributes["atmosphericCorrection"]) ]]>

P.S. in the last minutes, my requests are again being processed successfully…

The upgrade of the service, which we did today between 14:30 and 15:00 caused a disruption in specific cases (if one of the layers had atmospheric correction set to FULL).
The error was resolved and services should be back to normal.

I apologize for inconvenience.
