Suddenly: Couldn't connect to Tidbyt's servers

I’ve had a first-generation Tidbyt for several years (3?) at this point and I’ve suddenly not been able to connect with my Tidbyt as of two days ago. When I go through the setup process on my phone, I just get the message above saying that the internet connection is fine but it can’t reach Tidbyt’s servers.

Has anyone had this problem recently? I see some past topics on this issue and I’ve tried the solutions mentioned in there, but nothing seems to work :expressionless:
