Attention: Before reading further, first ensure you have APT 21.0.1 or higher. Previous versions can no longer connect to STScI.
Depending on your institution's computer security measures (firewalls, blocked ports, etc.), you may initially have trouble while using APT. This could include:
- Not seeing some of the documentation which is hosted here.
- Not being able to retrieve investigator addresses from our database.
- Not being able to submit the proposal.
Since it would be best to discover any communication problems well before the Phase I deadline, here are the steps to diagnose and fix communication problems. You or your system administrator can run this early on if you have any concerns about whether your institution's security measures might interfere with APT.
