Error 404--Not Found From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

Question

I installed 9.1 HCM with peopletools 8.52.
Everything was working fine - I sat up the process schedulers and reports were posting ,I built few pages ,menu etc and registered them and inserted data etc.
Then I decided to setup the Integration broker.
First I ran datamover script - appmsgourgeall.dml to clear the application messaging queue.
and I renamed the local node from PSFT_HR to YACINE_PC_HCM
and I configured the gateway
http://yacine-pc:8000/PSIGW/PeopleSoftListeningConnector
and the status was active.
then loaded the connectors successfully.
In the final step I went to the gateway propreties and I put the app server url //yacine-pc:9000.
user name:PS and pass:PS etc
and added the new node name - I clicked on Ping and it failed but I saved it anyway.
and from there the PIA stopped working .
I restarted the app server the PIA and I even reinstalled the PIA but it always gives me the same error
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

Answer 1

For the record
I did fix this error shortly after posting this Thread.
I edited integrationgateway.propreties and I removed the node definition then I redid the setup of the node by adding authentication to it.
Removed lines
