Stream returning 416 when entering any timepoint

E.g. "https://stream.companieshouse.gov.uk/companies?timepoint=1589932800

That timepoint is invalid for the companies stream.
As a test you could connect without a timepoint and record the timepoint you receive from us.
Then re-connect with that timepoint.
As an example a time point for the companies stream, for approximately 12:12 on Thursday 21st May 2020 would be 10138785

Hi Mark
Can you please explain how we get a valid timepoint value, i tried your example with my stream key
https://stream.companieshouse.gov.uk/companies?timepoint=10138785
