Problem description
Phoenix Management Console displays registration error during registration of Phoenix File Server Agent after providing the activation code.
📝 Note
Error displayed Error Registering Phoenix Server. Error: Internal error. (#100000001).
Cause
This issue might occur due to the Firewall enabled on the server.
Resolution
Perform the following checks to isolate and resolve this issue:
Check if the token was copied correctly from the Phoenix Cloud server.
Check if you are using an old token which has expired. Check from Phoenix Cloud Server > Manage > Activation token list.
Review the firewall settings on the server where you have installed Phoenix Agent.
To resolve this issue, make sure you have created a rule with *.druva.com for port 443 traffic for all Phoenix related communication.
This will help to register the server successfully and configure it for backup on Phoenix Cloud Server.
