Getting the error while adding backend settings in App Gateway that maximum limit allowed is 100. Can we increase the limit of adding backend settings in App Gateway
100 backend settings in App Gateway is a hard limit and cannot be increased. The recommendation here is to deploy another Application Gateway.
