Identified

We confirmed that this is triggered by a new pyqwest version (0.7.0). As a mitigation you can pin to an older version (e.g. 0.6.2). We are working on releasing a Tinker SDK version with a patch.

Investigating

Tinker SDK calls may be getting stuck. Eventually they fail with errors like client error (Connect): invalid peer certificate: UnknownIssuer . This problem has been observed primarily on MacOS.
