Recover and start up Portal for ArcGIS if the incorrect forward proxy information was configured in portaladmin

Summary

A forward proxy server is a computer on your Local Area Network (LAN) that allows connecting to an outside network without compromising the security of the internal network. Use of a forward proxy server is common in perimeter networks (also known as demilitarised zones [DMZ] or screened subnets) to protect the identity of internal machines. If your organization uses a forward proxy server to connect externally, you can configure your portal to use a forward proxy server.

The forward proxy server details can be updated from the Portal Adminintrator Directory by navigating to System > Properties > Update Properties, as outlined in Configure your portal to use a forward proxy server.

If the incorrect forward proxy settings are specified in Portal for ArcGIS, you may not be able to sign in to Portal, which prevents updating the forward proxy settings, effectively locking you out of Portal.
