You can open this site directly from the IBM RPA icon in the SysTray (next to the clock).
If I'm not mistake this page was changes to https://localhost:8099/web/en-US/ibmrpaclient

If the site is still inaccessible, it may be that the computer has a policy or antivirus blocking port 8099 from opening.
Another possibility is that the certificates for this port may have expired.
In newer versions, the IBM RPA service regenerates these certificates.
In this case, you can check the certificates by opening Computer Certificate.
