Connectivity between IB and the TWS has been lost. TWS or IB Gateway lost its link to IB servers, for example an internet problem, the nightly reset or a competing session.
Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.
How do I fix 1100 (connectivity lost)?
Wait for 1101 or 1102; check your connection and that no other session has logged in.
