So I've had this docker for a long time. But eventually, like months, it will just shut itself off with no warning and no visible errors. I've lost data before because I had to delete and reinstall and setup. I cannot use the same configuration as last time. Once set up, the docker works and everything goes off like normal....until it breaks again. Each time this happens, I try to update it and that doesn't fix anything and it makes no difference. When it's in this state, I start the docker, I can access for about 4 seconds then it shuts off. This has been going on the same way for years. Any idea?
