Can’t download sentinel 2 data

I want to download the sentinel 2 level2 data but facing the issue, sometimes facing the invalid key issue and sometimes only blank page shows
Invalid key (f7761ca2-63e5-4419-9d90-2063039e0377) to access Products

Could you provide a bit more information on what service you are using (EO Browser, API, Python libraries…) to download the Sentinel-2 data? If you describe the steps you are performing, this will help us provide useful information to fix your problem.
