Web Player upload size problem "413 Request Entity Too Large"

For instance, you may find that you cannot upload xls files bigger than 1 MB to Spotfire Web Player, but the files work OK in Analyst.

First reproduce the problem. Then use the the web browser development tools, to capture the network traffic.

The traffic may indicate the error comes from "nginx", with the error "413 Request Entity Too Large".  Also consider if there is a proxy between client system using the web browser and Spotfire Server, check its settings.

Nginx by default rejects upload packets bigger than 1 MB.

This can be changed by editing the nginx configuration value "client_max_body_size". Further information available here.
