Endpoint Error: Connection is not valid

I have two Stardog Free endpoints where I'm getting error "Your connection to Stardog is not valid, please ask an administrator to verify your username has access.":

Both were re-added to the respective accounts yesterday and working fine. However, since today, both show "Network Error" and "Unauthorized" similar to below. Could you help me trouble shoot it?

Hello and welcome to the Stardog Community!

It looks like both your Stardog Free endpoints were reclaimed. Our policy is to reclaim Stardog Free Knowledge Graph endpoints after 7 days of inactivity. We send a notice at 3 days to your email notifying you that your endpoint will be reclaimed.

To reset the timer and keep your environment, you need to log into your Stardog Cloud Account every 7 days. Alternatively, you can subscribe to Stardog Essentials — all the features of Free in a more powerful environment and no activity requirements.

Thank you,
I will move to stardog Essentials.
