Homey losing connection to google nest Hub

Update;

It seems that all functions keep working execpt casting something to the hub. I made a simple test flow (start flow switch light) wich always keeps working. However, casting a new webcam stream or camera snapshot seizes to work at random times. Restarting the cast of homeydash also doens’t work anymore at that point.

A ptp of the google hub still fixes everything for a while. To me it looks like the problem lies in the casting part, but i’m not sure what to try next.

Any thoughts?
