Yesterday my OneDrive (not OneDrive for Business) stopped syncing and I couldn't login to any of the sync apps. After a day of testing/troubleshooting, I tried connecting using my mobile phone hotspot and it works. Looking at the forms, Comcast has blocked OneDrive on occasion, and it appears it went to my connection now too. How do we request that this is removed so we can use OneDrive? OneDrive for Business syncing works, but OneDrive for personal accounts does not. @ComcastRachelH can you have engineering take a look at this?
Try disabling the Xfi Advanced Security feature as a work-around for now. It's buggy ! And there is currently no way for an end-user to be able to whitelist anything;
I spoke with Comcast Advanced Security support and apparently, they created a case and would be lifting the block against the service within the next three hours. @ComcastJason or others, is there a way to prevent this in the future aside from turning off advanced security?
