HTTPError: 404 Client Error: Is there anything I can do about this?

Hello everyone, we are experiencing problems with mars retrieval, in essence the error is:

requests.exceptions.HTTPError: 404 Client Error: for url: https://cds.climate.copernicus.eu/api/v2/resources/reanalysis-era5-single-levels

I will include a more detailed error output in the end. This error started today with all my requests, after they had been working for some days after the last mars problem got fixed during the weekend. So nothing except date had changed in the way the requests had been parsed (by flex_extract). Anyone know if this is a mars issue again, or some problem I could take care on my side? My colleague is having exact same problem with his similar configuration, neither of us have changed anything but date of the requested data.

I have checked that .cdsapirc file is in order, I have also defined the CDS_API_KEY and CDS_API_URL env variables with the key and url. So the way my CDS credentials are stored and accessed locally hasn't changed at all between the working and non working condition.

Any help is appreciated!
