Yesterday it worked normally in the morning, I logged in at 7 am, downloaded Lora, did inpainting, generated images, downloaded models, everything was normal until disconnection after 4 hours of use. I suspect that the code is normal, but the colab system is giving priority to the paid versions, when not many people are using colab, mysteriously the free accounts start working again, just theory.
As for runpod, if you create the code let me know how to test it, I just looked and the cheapest version with 16gb of vram and 23gb of ram costs: $0.34/hr.
