Your phone stores temporary game data (assets, images of buildings, friend lists). If this cache gets corrupted, your game client sends "garbage" data to the server. The server rejects it, and you get the 1100.7 error.
During "Black Friday" sales, "Mayor’s Pass" season launches, or "War" weekends, EA’s servers get slammed. When millions of mayors log in simultaneously, the server queue times out, generating error 1100.7.
If you have tried every step above (Airplane mode, DNS change, cache clear, VPN off, hard relink) and you still see error 1100.7 after 48 hours, you need official help. Go to EA Help’s website.
