The February 2025 monthly average data was updated a few hours ago. I am trying to download this data but I am getting this error.
However, this error only occurs when requesting the data for February 2025, it doesn’t occur if I try to request the data for January 2025, for example.
When accessing the data in the link below, the data update date is today, and when selecting the options, February 2025 appears as available. Why is this error occurring?

Same error for me. No luck using the API either.
The same for me. It is funny, but if we ask the same for march 2025 it doesn’t gives any error. May be a bug ?
It seems to work now. I just ran my script and it didn’t give any error. 
2300 UTC March 8 and access fails with the GUI and API.
Hi,
Could you please try now?
Thanks
Could anybody help me with the new time format with ERA5, and convert it to standard calendar (ymd)?
The data format until recently was (ymd) X20110101, X20110201, etc., but now it is X631152000, X633830400, etc. I use R to download the data and my analysis. Could you please help? Thank you

I am also getting similar errors. Happens both in Python script and through GUI. I am trying to request all of 2025 that exists:
