System Updates Error 500

Hello everyone. I am unable to update my device, even though I have activated the remote controller. I checked the ADC log file and saw that the CubePilot OTA server is not responding to the request. Please help—what should I do?

I noticed recently that the site was hit by a DDoS attack, and it is possible that many services were taken offline. However, I urgently need the certified firmware; where can I download it?

Currently, I am running version FRU01240530.
