For security reasons, the NEOS browser interface disables AMPL file-reading commands like “model T3p1.mod;”. That is why the model statement in your run file is rejected as an error.

If you have a data statement that reads a data file, you will need to also remove that from the run file, and specify it instead under Data File.
