Welcome into the Community and thank you for posting for the first time
I'm very sorry to learn about the error in the home, this must be frustrating. The C501 errors can indicate network issues at times but I would need to investigate this for you more in-depth. I was unable to access your account and will need some additional information to access your account and run some preliminary checks.
