Thanks for bringing this to our attention! We are working on bringing the page back up as soon as possible. If you can't wait, please send me an email at firstname.lastname@example.org and we'll get this sorted out ASAP.
We were able to bring the website back online, and it can now be found at connector.timeseries.com.
We’re still working on the email that’s being sent to you when you request your API key, since that still contains the old URL, but the API key should work so you’re good to go!
Thanks for bringing this to our attention. I’ll make sure to update the AppStore module’s documentation to reflect these changes as well!
