Get Output Service for other systems after donation does not work

Hi.
I want to retrieve public data of systems other than mine, but it seems not working after a donation.

I expected that after the donation, I would be able to run Get Output Service for any (all) systems, but it does not work.
I read in the donation section that after donating, “The sid1 parameter is enabled to retrieve daily generation data from any system.”

After I donated 25$, I cannot read data from public systems that are not mine.
For example, with the request
https://pvoutput.org/service/r2/getoutput.jsp?key=<my_key>&sid1=63030
I receive the error “Unauthorized 401: Invalid System ID”

However, before and after the donation, I read data from my system with the parameter sid (not sid1).

Am I doing something wrong?

Thank you for your help.

This also requires your own sid -
