Eclipse: Native proxy setting goes missing, breaking network connectivity

Question

For no discernible reason, the native proxy provider (see pic) of my Eclipse (Photon 4.8) sometimes goes missing. This results in Eclipse no longer having internet access. I have not found a way to add this provider again except restarting Eclipse.

My main two questions are: Can I add this provider again once it goes missing? What could be the reason why it vanishes in the first place?

Answer 1

At the bottom of the Network Connections dialog, you should see a Restore Defaults button. For most cases, that should suffice.
